I went with the R2C's only because of the ease of install and maintenance. They sound great, and the car feels a bit more responsive in the mid-range (according to by butt-dynometer).

If you don't mind the extra work to install and service the filters, then go with the Stillen Gen 3.

 

+1 ^^^

 

i dont run the rain shield and i have never had any problems

 

I live in Seattle where it rains a lot and I have the Stillen Gen 3. The shield does work really well. I've also washed my car and sprayed the grille with a hose and the filters remain dry.

 

I was looking at a Stillen Gen 3 as well, but then there's this: Amplified Motorsport - AmplifiedMotorsport.com - performance audio auto accessories which is one piece, and supposedly doesn't require cutting like the Stillen does.

Anyone have one of those Takeda's installed? How is it?

 

i have R2C CAI as well it sounds amazing and you could feel some difference in you performance.
but i if your looking for the most HP gain i think the stillen Gen 3s are the best

 

top secret....

 

No experience with any of the others but I love my R2c's...great sound when your on in quiet when you aren't.

 

^ i agree!

 

Hmm, might have to go with the R2c. Ease of install and maintenance plus I won't have to worry about water. Rains a lot here in the PNW. I'm not really concerned about top end HP gains from long tube intakes. Mid range usable power that R2c gives is more beneficial for me.

 

You dont need to cut any plastic to install gen 3?

 

you do, the intake holes have to be cut to pass the tubes through. So once you put the gen3's on.. just never take them off cuz I don't think those inlets can be replaced

 

What? You just make a slight enlargement to pre-existing holes in the composite fiber core support, and if you reinstalled the stock intake you'd never know the difference.

We've had several owners who have purchased used cars and the Gen 3, went to install it an found that the holes had been enlarged from a previous install from the original owner. I'd have a look at the installation instructions if you're unclear of what's actually happening.

As far as the filters, K&N recommends 50,000 mile cleaning intervals, but most enthusiasts will do it sooner. But even at 30,000 miles, that generally 2-3 years for most people, so limited concern.

No issues with water, with the location of the filters, and for extra measure a urethane rain shield. Guys have driven all over monsoons and had no problems. If you're paranoid, you can always go with a pre-filter on the conical filters for additional protection.

As far as power, I'll let the forums do the talking, there are dyno's all over this forum, the 370Z, 350Z and G35 forums to back the gains..

 

There you have it. I didn't have to do any permanent modifications to my '10 sedan. Just careful fitment and some minor isolation with foam/neoprene. Maybe I'll have to change out the neoprene after awhile, but that's better than anything permanent.
