Here is a review and some pics of the K&N Typhoon intake and some preliminary test results. The results were taken with an OBD2 scanner to note the difference of outside temperature, air intake temperature during idle, cruise and WOT. I started the test when coolant temp has reached to operation temp of 185F to 187F. Both before and after tests were done from a cold engine start to eliminate heat soak from a long running or idling engine. However, please keep in mind that the two tests were done on a different day with different outside temp. This test result is only meant to be a comparison of outside and intake temp.

Before K&N installation:
Engine coolant temp = 185F to 187F
Outside temp = 48F
Intake temp @ idle = 68F
Intake temp @ cruise speed of 65 MPH, 3500 RPM = 64F
Intake temp @ WOT from 2500 RPM to 6500 RPM in 3rd gear = 66F

After K&N installation:
Engine coolant temp = 185F to 187F
Outside temp = 39F
Intake temp @ idle = 46F
Intake temp @ cruise speed of 65 MPH, 3500 RPM = 43F
Intake temp @ WOT from 2500 RPM to 6500 RPM in 3rd gear = 43F

K&N intake noise level:
Q: Is it noisy during idle?
A: I didn't notice any additional noise during idle at all. The noise from the the cooling fan, and normal engine sound are much louder if there were any intake noise to begin with.

Q: Is it noisy while cruising?
A: No noticeable noise increase while cruising at part throttle all the way up to 4500 RPM.

Q: Is it noisy while shifting?
A: I did some quick 1,2,3,4 shifting part throttle up to 4000 RPM without noticing any additional noise.

Q: Is it noisy during decelaration?
A: No noticeable noise increase during deceleration from cruising speed.

Q: Is it noisy during downshift?
A: No noticeable noise increase during downshift to 4th from 5th (3500 RPM) and then part throttle back to 4500 RPM.

Q: Is it noisy @ WOT?
A: Noise? Are you kidding? The sound it emits is the sound of a healthy breathing engine unleashed! The intake sound level increases ONLY if you put the pedal to the metal. The sound is noticeable starting at around 3500 RPM during WOT. It actually sounds very sweet like a fine tuned engine with a nice hum. The sound level continues to increase to a little pass 6000 RPM and it changes tone when VTEC kicks in. Then the real animal inside the engine comes out to play and revs all the way to redline! This is when you wish the redline is higher so the fun won't stop!

Q: Do you feel the HP or torque increase?
A: Honestly, since the car is so heavy, I can't say that I notice any HP or torque increase. I was too occupied enjoying the engine sound @ WOT! However, I'm planning to find out on a dyno.

Here are some pics:











I decided to slot out the fog light cover for more air and installed a mesh behind it to keep the bugs out.


K&N uses some very high quality hardware for the installation. It uses 100% factory mounting location and retain 100% of the factory emission connections.

nice work how did u slot the fog light cover what did u use i was thinking of doing the same ti mine but dont have the tools atm

tsxer.ca

will it void the warranty?

accsuperstar

dang that looks sexay

TinkySD

taht's some good IAT info. Factory dyno for the k&n looks just like the injen which makes sense since they are a similar design.

Ah...so you did slot the intake cover...what tools di dyou use?

Also is the k&n a 3 inch pipe?

I used a dremel tool with this funny looking bit in the pic. I drilled a hole at the corner of the slot from the rear side of the fog cover. Then I used the cutting bit and just cut around the slot to create the opening. Btw, the cutting bit cuts the plastic like butter. I later used a file to smooth out any rough edges.



TinkySD, The dia. of the pipe is about 2-5/8 or 2-3/4.

tsxer.ca, It depends on what the warranty issue is. If the mod directly or indirectly causing a problem, then it can be a problem with the warranty claim. However, if the problem isn't related to the mod, then I wouldn't worry about it. After all, I can easily reinstall the stock intake system prior to taking it to the dealer.

Jtso can i borrow your dremel??? lol we live in the same area =)

Dan Martin

Looks good! I like that red.

I have a dremel

Great write up. Thanks for the sound details and enjoy the intake.

Where did you order and how much if you do not mind?

JTso

iTrader: (2)

I ordered mine from one of the online K&N dealers here http://www.knfilters.com/typhoon/TyphoonOnline.htm . They are all about the same price with free shipping ($211.97). However, I later found a lower price of $185 after I received my order. http://shop.store.yahoo.com/hopup1/enpe19.html .

The blue one should look pretty good with your car.

AZTSX

what is that stuff around the filter?? jw thx

illmeltxwithyou

Helps against water. Yeah that red looks bad ass man. I'm kinda bummed out though you really havent noticed a difference. I've been hearing that the K&N is actually better than Injen ect ect. I think the last dyno I saw for Injen was 12hp. Hopefully the K&N does better because it looks tits

The black cover is called the dry charger to help prevent water from contacting the air filter.

I'm sure the power increase is there, as indicated on the K&N dyno sheet. It's just not very noticeable to me, as I'm used to driving a supercharged Civic where power and torque are very noticeable. The kind of power that will throw you back to your seat.

dabuda

nice, where did you buy the dry charger? and is it universal? looks like it, thanks!

gsclifton

iTrader: (2)

Here is the part Part

You can order them at 4filters.com for $28.46, but they may be cheaper somewhere else. I have ordered from 4filters before with no problem.

The drycharger came with the intake kit and it's not universal. This particular p/n is RX-4730DK and it fits filter size with a 5" top, 6" base and 6.5" length.

If it's the same size as yours, then you can get it from here or here

HTH...

Jab31169

I've said it before and I'll say it again....THE DRYCHARGER IS A MUST HAVE!! The area were the filter sits after either of the cold air kits is not watertight at all. I had to special order the drycharger for my injen filter. I have the part #'s at home for that one if anyone would like it.

xizor

I'd appreciate the #'s, a drycharger would help keep me from being apprehensive about driving around in this wet VA weather.

Faid

I dont mind the P/N either
if i install it do i have to take the bumper off again??

Faid

Also was woundering will the drycharger decrease the HP of the car??

JTso

iTrader: (2)

You shouldn't have to remove the bumper. Just remove two bolts and three plastic rivets, then peel back the wheel well liner to gain access to the filter.

dabuda

thanks for the info gsclifton and jtso!

yes please, i'm planning to get the injen filter thru the importave GB. we have sporadic showers where i am so the drycharger would be a must. but it wouldnt be much help in 1-2 feet of water right?

Dan Martin

nope!

AZTSX

i would also like the #s plz although it doesnt rain here often i am cautious cuz when it does it usually rains hard.. better safe than sorry right?

yrbzephyr

Jab, have you found the part number for the Injen drycharger? Thanks.

NeoChaser

would u have to forgo the fog lights if u install a CAI?


also would u mind telling me if u lost any torque after the install?

TSXTim

Dyrcharger part number is listed here. RX-4730DK

I ordered the red one from Hopup.

Today I got to ride in and "race" a TSX with K&N intake and here are my impressions. First, I cannot dispute the dynos and results posted, and, in fact, these result have had me truly considering this modification to my own TSX. The modified TSX is just like mine (5AT non-navi). Seat of the pants feeling from getting out of mine and into my friend's - no difference. Sound: Noticeable wonderful sound difference at higher revs...no real difference in just normal driving. Now here's where things get weird.

We informally "raced" each other. My TSX was quicker off the line and at no point lost groud to my friend's TSX with the intake. Both of us just flooring the pedal and going. There certainly was no real difference in performance that we could assertain after about 15 minutes of "cat and mouse highway tag."

Without a doubt the high RPM sounds are wonderful with the intake, but, from my own personal observations, I would not spend the money based on a performance gain...but then again..it did sound awfully nice.

yrbzephyr

Do you two have similar mileages on your cars? Maybe your car being more broken in than your friend's may have given you a performance advantage that offset the CAI's performance increase. Can you think of any other differences between the two TSX'es that may have made a difference? Plus, it was in CAI mode, right?

Jab31169

Based on my personal observations and that of a dyno run...I do belive an intake is the best money you can spend on this car. Now I dont know if the automatic is that much of a dog or what but I do know that the intake made a crapton of a differance between stock. And so says the dyno:

dom

Jab, Injen Automatic dynos show a 12HP gain, just like the 6MT TSX.

I don't think I'll get an intake until/if Hondata becomes available. I don't think the Intake alone is enough to noticeably affect performance, just like SilverTSXinPA has observed.

KJLite

as mentioned previously, if your cars don't have similar mileage and both stock tires, etc, can throw off results. also keep in mind that no 2 cars are alike. each car will be slightly different in terms of performance. your car may be a fast car out of the production line, while your buds is nml. 10-12 hp is not gonna lead to dramatic performanc egains, but couple it with exhasut and new rims/tires, and you could have some substantial gains!!

the only way to tell is to do before and after drag times. dyno results don't mean shit if the car is not any faster.

SilverTSXinPA

Within 700 mi: mine - 10,500+ friends 11,100+

SilverTSXinPA

I guess that is my point...if there are any performance related gains, it would take some type of precision measurement to determine them. I do love the sound @WOT and may do it just for the aural sensation, but, as far as doing it for a seat of the pants sensation...nope.

JTso

iTrader: (2)

It will take more HP than the intake alone to feel a difference. However, installing the intake is a step in the right direction.

SilverTSXinPA

Domn et al: I am not in anyway saying that is a meaningless upgrade, I was only sharing a seat of the pants observation. I have been following the threads related to intakes and dyno's and was simply implying that I was disappointed in what I personally experienced. I also do not consider the automatic a dog either...taller geared, yes...dog, no. I do agree with domn that something in addition i.e hondata flash would be needed to experience a seat of the pants gain. I too will probably hold off until such an upgrade becomes available. Until then, I will just turn up my stereo and enjoy the ride.

tsXgtp

Dam, that intake is killing itself. I have never seen so many bends before. That 90 degree bend is like adding 15 feet of straight pipe to it. Id like to see a short ram, with a filter right where the first pipe meets the second with the black adapter. No vacuum, and the temp isn't going to make all that much of a difference.

JTso

I'm sure you will find many people disagree with you. Temperature has everything to do with engine performance. That's the whole idea of cold air intake by routing the air filter to the lower part of the car away from the engine compartment (heat source). Have you ever heard of an intercooler used on a turbocharged engine? Btw, the intake system also allow for short ram installation but performance is suffered.

Dan Martin

Nothing like a head to head dyno to prove it. Should be pretty easy if someone has already installed it as CAI. Just a matter of changing filter locations.
