New member shout-out, cold air intake options?
Hello everyone! I am pleased to join the community. I am picking up my 08 RL w/ Tech Pckge today and I am really pumped. Blck on Blck combo...a super sexy combo (when clean 
)
I had narrowed my search down between the RL and a Lex GS350. Ultimately it came down to the $6k cheaper price of the RL sealed the deal. Besides the price difference, although the GS definitely had a more responsive gas pedal in the lower RPM range, I couldn't get over the fun of utilizing the paddle shifting in auto-manual mode. Also, despite many people thinking the RL exterior design is somewhat understated (present company included at first) when I first saw this RL in person I loved it!!! I was hooked the minute my eyes spotted the cross-drilled & slotted rotors and large front brake calipers. I don't know if that is standard on 08 RL, but I love that look. I had a gen 1 '02 Lex IS300 which was modified pretty heavily (also black on black with cross-drilled and slotted rotors) so I look forward to seeing what is realistic with the RL aftermarket community.
Given we are dealing with a Naturally Aspiring (NA) 3.5L, my first order of business is to see what we can do to add a little more pop in teh lower RPM range. What are the options to put on a cold air intake (or at a minimum a less restrictive air filter) and exhaust. What are some options people have utilized with decent results?
Also, this car is sitting at 90k miles. I haven't reviewed the recommended service yet but anything major around this mileage I should be looking at?
Cheers!

generally, a cold air intake wont do squat!
you want to look at exhaust upgrades to feel a little more low end.
I know RV6 performance sells an aftermarket jpipe for the RL.
and then you could look at changing out the stock exhaust to something with mandrel bends instead of crushed bent pipes.
Generally speaking, most mods to the J35 just push the power band up.
VTEC powa!!!!!!!

Welcome! Amazingly, you are not the first person to own an RL or want to put a CAI in it. (Hard to believe; I know.) Please learn how to use the "search this forum" tool.
If you want some more power, you should do pre-cat delete, j-pipe, high-flow cats, and cat back. THEN worry about getting more air in. Acura designs their intakes well and all you will add without opening the exhaust is sound.
Heavy has made a great point though. You did not buy a sports car that is luxurious. You bought a luxury cruiser that can be sporty. If you want to "heavily modify", get out now.

I appreciate everyone's comments. Believe me I am well aware I didn't buy a sports car, nor was that my intention. That is why I didn't ask about supercharger kits :-)
Great feedback on the already well designed in take and to focus more on the exhaust side first. The IS300 was the exact opposite, so I appreciate the direction. I also need to be careful what I do on the exhaust side since I am in a county which still has required eCheck....AMAZING I KNOW! So some of the cat removal approaches may or may not be the right idea for now. I will continue to do some more thorough searching.

Actually, the CT supercharger is the best mod we have seen here and turns the RL into a sports car. That's a great idea if you have the $$$.

^meh.
very inefficient. with this specific supercharger, it takes about 40hp to make 40 extra hp.
the little MP62 is not big enough for the J32, much less for the J35. you could retrofit the MP90 onto the J35 tho. that will make more power.
heat is the killer of all things and without proper watch guards in place, the engine will blow. (intercooler or meth)
and we're close to having a tune but no one has applied it to the RL yet.
I have been toying with the idea of picking up a higher mileage RL and turboing it.
an AZ member has successfully turboed the RL engine(or was it the J35 from the TLS?) and dropped it into his accord.
and he's local to me too!
imagine SHAWD with about 500hp!
if I could pick up an RL for less than $5k, I'm so down.

I bought a Ebay CAI for 3rd gen TL and threw a K&N on it. did not notice much until i got the High flow cats and J pipe.

the turbo J's are awesome!!!!
a lot of power can be made. we've seen 500hp at the wheels on a FWD 3G TL.
unfortunately, at those levels the FWD is pretty useless.
if we can do that without stressing the AWD system on the RL, she'll be a fucking bad ass car.

Don't make me bring Maury Finkle I here.
parts of the drive train untouched. I saw this as a testament to the RL's unrecognized abilities.

I wish I was boosted...

The supercharged Odyssey is a new one even for me, and anything with boost and a j-series normally does not. I'm assuming that is the Ridgeline super-c that was made by CT? Absolutely beautiful in there man. Tried to talk my wife into allowing me to boost our 2010 MDX and was going to have Matt fab up the manifolds but she wouldn't budge. So I ended up taking it to work one Saturday and through on a 100 shot...hehe. She still has no idea why the car suddenly gets faster when the cruise engage switch is pressed...if I forget to turn off the activation switch.
The boosted Odyssey has been around for a while. If you go to their (Honda manufacturing of Alabama) FB page, they have dozens of build photos of this. These guys also did a 3.7 swap on an Accord as well. Here's a few pictures...
And then a few others that do similar style of racing...
This is a 350hp TSX that has the j35z engine with cams.
And another TSX, not sure of its specific mechanics but here's....um, half of it. Built by HPD obviously.
Oh and Justin, come on with the RL already!

We are also interested in trying to turbo our RL. My husband had said something about cold air intakes as well, trying to open it up so we can get better mpg. Any success? Also, if you were to go with the turbo option, what are we looking at cost wise for that upgrade?

Modifying the intake will do almost nothing for your MPG. Buy low rolling resistance tires, and inflate them to 36 psi. Just be prepared to not stop when you push the brake pedal.
I have to think that a custom turbo setup is going to run you at least $3k and risk the long term reliability the RL is praised for.

Thanks for the info. Certainly no point in dropping that much money and compromising the "integrity" of the car. I think I will stick to what I have. Im not upset about the mpg especially with the type of engine it is. That was more my husbands suggestion. The only thing I'm looking to change is the paint color honestly.

The engine and transmission are reasonably tuned for sport over mileage. Couple that with a weigh in of 4,000 lbs before people, and it takes some energy to get going. If you can just keep the car rolling at hwy speeds, 27+ mpg is possible.

Any other product competitors to RV6?

No one else makes anything for the RL before the cats. XLR8 and ATLP are the ordinary competitors for mostly TL, TSX and Accord. RV6 has dynos for the 3.5L TL Jpipe. What we have discovered over the years is that the SH-AWD doesn't like dynos. The results show 200-210 WHP stock. The best way to know accurate gains requires disconnecting the driveshaft and testing in FWD.
The 4G TL is the closest to the RL. Here is a link with some good information about mods and their gains but not necessarily suppliers. https://acurazine.com/forums/4g-tl-performance-parts-modifications-295/pseudos-guide-adding-power-your-4g-854092/
