Comments: Finished my cold air intake with heat shield and installed it. The difference..... WOW!!!! It has a lot more throttle response over the whole power band. It will now break the tires loose from a dead stop. The exhaust note is deeper and more aggressive sounding. Oh and there is a nice whir sound every time I give it some gas! Also I gained about 3.5 mpg by doing this. My average before was 16.7 and on the same trip with the same weight and amount of fuel and cruising at the same speed I was averaging 20.2 mpg. Not bad for a v8 with the np249.

Comments: 90 and 45 degree bend, and CCV tube. K&N Filter next to radiator for some nice cold flow

Price: $57.00
Recommended? Yes

Comments: I made a cheap and easy cold air box by cutting a sun deflector shade into shape as a heat shield and also wrapping part of it on the intake tube. I then cut out part of the air box to give it some more flow. Oh ya, and a drop-in K&N. Sounds great and seems to help quite a bit!

Recommended? Yes

Comments: This a copy of the AEM/K&N intake. I have access to a mandrel bender. I used 3.5" tube for the charge pipe. Fabricated some sheet metal as a heat shield. Also covered up the hole below the air box to avoid water intake.

Comments: only cost 60 bucks total..using an autozone coupling, which was clamped on to a 90* 3 inch diameter tube..coupled and clamped to a 2.5 inch piece of pipe off a cut up civic intake..with an AEM filter on the end. works great..sounds good..helps with throttle response and acceleration it seems like..judging from my butt dyno.

Comments: Yes, eBay. Haters go away. Money is tight. Got a simple long tube intake, with a great filter. Eventually will get an AEM Brute Force intake. But for now, this works wonderfully.
