RDXturbo07

i was looking to get an intake after my i got my reflash and was wondering if i should get the k&n typhoon since they stop making the CP-E

littleblazer

You can buy little less on ebay. I love the sound k&n typhoon make.

RDXturbo07

i jus got one off ebay thanks! paid 224 for it... do u have any problems with heat soak or the heat shield does a good job?

Kaze66218

The heat shield does a decent job separating the intake from the engine bay without the reflash It sounds like darth vader, I miss it...lol, my kid really liked it.

Does anyone know if the K&N Cold Air Intake will work on the 2010 model. The reason I ask is because I only find models on eBay for 2007 and 2008. I'd hate to spend $300 on an intake and have it not fit.

Kaze66218

The engine is the same for all models the engine does not appear any different you should be good. Weapon r is cheaper and put an AEM dry filter on it if you don't like the foam! Bet the weapon r sounds better.

SinCity

My wife found it too noisy.....and then I started getting tired of it. Sold to another user.

Fightnpuma

SinCity... what did you get? The K&N Typhoon, Weapon R or the CPE?

You're better off doin a silencer delete. If you want the noise. You would want to run a cai since its bennificial to have your maf reading a cooler intake temp. When you are suckin in hot air from the engine bay the maf would detune you a lil. And im not a fan or k&n at all. Hold one of their filters up to a light and see why. When they get a lil old like a few months old they have big enough holes that ants could fit through it

Agreed k&n fliters do get like that. That's why I suggest aem(no oil-- at all) air filters. Even SUS filters. I ran a sus air filter on my prelude for 4 years the ID of that filter doesn't fit the rdx K&n pipe. Doesn't fit my new turbo either.

Op--- Since you already bought one.. There are tons of air filters choices. If I could do it over again: weapon r with aem filter, g2g, sus was for off road and you'd probably not want to drop any more money than youd like to on engine rebuilds.

The IM has a intake temp sensor, unless there's redundancy with the mass airflow sensor.

windowlickingood

All mafs have a iat sensor. If there is another it would prolly have to measure the efficiency of the ic

BigHatch

FWIW I've never had anyissues with K&N style filters over the years.. Good thing is you get a heat shield.. if you like you can always buy any kind of fliter to go on it, which is probably easier than trying to source, build a heat shield.

Fightnpuma

I'm not sure but I'm thinking of getting the K&N Typhoon Intake, I like the fact that it has the heat shield. Plus I've had K&N on two of my previous vehicle and never had a problem with any of them.

I'm still wondering about the Weapon R one though, it is a lot cheaper.

^ what cars have you had them on? where they turbo'd? sure nothing catistrophic happened, but im sure that youre not going to see the fine grit that can get into your engine. I mean what do you do to make sure that nothing at all bad is happening to your car?

what you have to think about with using a k&n on a turbo car is the oil and dirt that will get on the maf. which then coveres the important parts that helps the engine run to its potential. this is not the same setup as a typical na car. If you clean your maf alot then you prolly wont ever have issues. but the point is that it still lets in way more particles into your engine thats going to help wear it down.

here is a gently used k&n filter.



dont know about you... but dont look like its very good at filtering anything besides large insects. the oil is supposed to help filter most of the finer particles but then you run into it just misting all over the maf sensor.

wspy

Sooo..what do you suggest using?

windowlickingood

ive been running amsoil air filter in my sti and its proven itself with the many trips to the dry lake bed here in vegas.. you can also reuse this filter. all you have to do is vaccum and air spray it out. but they dont make it for the rdx yet so im a lil bummed. but i would rather run a open intake than run a k&n filter.

windowlickingood

but yet again, amsoil does make cone filters that will replace the media on a k&n intake.

RDXturbo07

jus got the typhoon installed and sounds great !

oneonlywgs

You should re-check the flash once you put on the k&n. Unless your tuner has already taken the k&n into consideration with the previous tune.


the heat shield is only going to hold so much heat away.

RDXturbo07

well jus tested my 0-60 and 1/4 with my g tech got 6.0 to 60 and 14.63 1/4 so with the downpipe im hoping to get around 14.4 we will see wen they start making them!

noodle4rdx

i just got mine installed, and just curious if i'm hearing the same sounds, and if it is normal and installed correctly.
while i give it gas i hear the suction of air like darth vader and when i release i hear a very audible BOV sscheeeee. not that i'm complaining but i'm just curious if this is what it is suppose to sound like. oh and i def feel the performance gain along with hondata.

RDXturbo07

yup thats wat its suppose to sound like i love it i can hear the turbo more on my car now then in my bros evo but then again he doesn't have an intake

JCRDX11

I have the weapon r intake and was thinking about replacing the filter just to see if there is much of a difference.

What size filter do you suggest I get? any difference between them beside the size? (For na or turbo?)

I see AEM has a huge hp gain on a ms3; not sure how true is the video though.

SinCity

Typhoon. Now, I just have the K&N panel filter.

naster3

i like the price for the weaponR and throw in a tornado... LOL

Kaze66218

Sorry for the delay!

OD=outside diameter
ID= inside diameter

Been real busy, busier than usual. the od of the pipe should be the id of the filter. my K&N typhoon tube is 2.95 inch od so i'd need 75mm id filter. I just got back from the website love online pdf manuals and the... Anyway, you have a what appears to be a 3 inch(75mm) filter.

-- If that is true then I'd do a:
1. AEM 21-2038DK gives you a red 8 inch (street) cone.
(or)
2. AEM 21-2038BF gives you an grey 8 inch (off road) cone.

I'm gonna guess here but, the street might be higher flow than off road w/ it's higher filtration.

the best deals on these filters change daily, so I cannot give a recommendation as to where to buy them. Ebay has a lot of knock-offs, just FYI if you didn't know already.

Videos are for fanboys, dyno's are for ego's; but its worth something, to someone.

JCRDX11

I measure my weapon R and the filter is 5 1/2" L also it is already touching the computer.

I have to take out the filter to check the inlet size.
I try googling the difference between the street and off road unit.

Is all Street unit filter red?

Kaze66218

1.that intake pipe is longer than i thought, haha, and i wanted to do this too and is suprising that I havent looked into PN#'s

correction-- 5.125inch cone
- AEM 21-203D-HK => Supposedly red( 7/16th spacing????), Street
- AEM 21-203DK => Supposedly red, Street
- AEM 21-203BF => Supposedly Grey, Off-road
That'll git 'er dun.

2. don't have too, I checked the website for you. 3" inlet

3. I believe the grey/ BF/ Brute force is the balence of filter and power. The red/DK/ Dryflow is by my guess more baised on power.

back to thread. I noticed the K+N under the light in my garage and WindowLG is right, that is unsat! I used to have a bunch of KN filtersand none that never looked like that. Must be faulty qualility control??? dunno. Turbo goobles it up?

JCRDX11

i just measure and the weapon R inlet is 2.5 inch inside. Do you know which AEM filter will fit my intake pipe?

Kaze66218

SERIOUSLY omg????!!!! I looked at the manual online, said 3"?

http://www.weapon-r.com/files/manuals/301-160-101.PDF

2.5" in that case:

21-201dk - street 2.5" inlet
21-201bf - offroad 2.5" inlet

JCRDX11

Yeah man - I think the pipe is 3" but the inlet is 2.5".
I use the 3" to 3" coupler from the filter to the intake pipe.

One end where the filter suppose to link up with the coupler has some sort of clip holder.
The filter has some clips sticking out on the inlet outer portion.

JCRDX11

Here is the information I got from AEM - I order the Red Street gen -DK

All 21-201 dimensions are identical:
Product specification
Base Outside Diameter: 6 in (152 mm)
Flange Inside Diameter: 2.5 in (64 mm)
Flange Length: 1.5 in (38 mm)
Flange Type: Centered
Height: 5.125 in (130 mm)
Top Outside Diameter: 5.125 in (130 mm)
Top Style: Rubber
Top Material/Finish: None
Filter Material: Non-woven Synthetic

Here’s tha basic difference:

DK is the new red generation Dryflow media, that uses a structural screen wire to enhance airflow capabilities and make the filter incredibly easy to clean


BF is the original media in gray , designed for tough off-road applications, they are so durable that they maintain their shape under even the most severe abuse


D-HK is similar to the DK , except that it has a hole on the end cap for vehicle that use a sensor on the filter.



They all will work well with Turbo applications, the DK is structurally the strongest.

@all- FYI, I linked the AEM part numbers to google "shopping" search IYDK already. Should be able to find lowest price internet that way.

With a 2.5 inch ID I'm seriously glad I have K&N pipe... I ordered a replacement 3" airfilter from AEM for the RDX and 4"-er for the wreck.

To people that would like a intake heat shield INJEN has a heat shield that straps to the intake pipe. Click here

JCRDX11

Just notice - the K&N filter does not use a coupler between the air filter and intake pipe?

JCRDX11

Just re-measure my weapon r and it is indeed 3" plus the filter.

I am changing my AEM filter to 3" now.

I have a CP-E intake I just took off my 2007 RDX for sale.
The wife is driving it now and does not like the heavy breathing noises. No accounting for taste.
The RDX definitely ran better with than without it (sigh).

$150 shipped to the continental USA.

rpak1

so which intake sounds the best overall?

Kaze66218

The stock intake has baffles (sound mufflers) built into it that silence intake sounds. Idealy if you want a diferent sound, simmilar to the K&N for no money at all, remove the lower intake plastic that has a snorkel. A AZmember, HABU, touched on it-- free mod click-here , got flamed for it but he's right. In reality his intake is no different than a K&N, but where the problem is there is no heat sheilding seperating it from the engine compartment.

Sidenote: I experieced a 5-8 hp loss after 2 consecutive pulls with a K&N. The engine was heat soaked from the first pull. So weither the Dyno by the hour or by pulls, that will determine the cool-down time for the engine. Honestly there is no proof yet that by removing lower cowl for intake box will add power, It will add sound obviously, by removing the baffles though. If you remove the snorkel chance has it you will alow ambent heat to enter the intake charge. Higher heat leads to knock issues and retarded timing.

The design of the snorkel alows it to capture water and "other bad things" and keep it out of the intake charge and from ruining the filter element. The secondary design was to reduce intake noise, as the next item inside the snorkel is a baffling material.

You can spend 200+ for a custom tube, K&N or what not, and that alone gives you a reuseable filter option. I personally don't like the K&N filters anymore but they work decently for a while.

A Pw:JDM Whale-penis (IF IT WAS AVAILIBLE) intake on a RDX that would sound sick.

Does anyone thinks this headshield would help at all? -

kn intake didnt add any horses to my rdx...only difference i noticed was more engine noise. i did get a lot of improvement with atlp exhaust, car felt more responsive but still i did not gain any horses. the only mod on my rdx that improved horsepower was the hondata flash.
