Question:

Cold air intake kits for Infinity G35 03 coupe?

I know zero about cars and I wanted to buy one for my boyfriend. Can someone find me the best one for the best price? Or tell me which ones to avoid? Thank you!

Answer:

There are two decent kits you can buy depending on your price range. 1. Stillen air intake kit- Its about 260$ and it will pump out about 5 hp for coupes. It also comes with the Z-tube which might add about 2 or 3 more hp. Its a good intake, I had it before I changed it out. 2. Injen air intake- This one cost about 300$ and will probably get about 8-10 hp. This one is a bit more better because the tube curves down into the air duct letting the filter take in more air. As far as water leakage I haven't heard these products ever having that problem so I wouldn't worry about it. Hope this helps.
The G35 already has a chilly air intake. Aftermarket intakes in this vehicle basically substitute the sound slightly; they do no longer something substantial to the flexibility curve. in keeping with danger a million-2 HP at maximum, which you will by no skill be conscious. a extra suitable bang on your greenback may be the MREV2 plenum and a plenum spacer. 15-25 HP mod.
Take it from an expert cold air stuff is wasted money on 95% of cars made in the last 15 years. My friend has a dyno at his shop and we like to see the difference in peoples cars he/we dyno. Like in this case we have OH so many times looked for power gains with KN filters. We have never seen any proof on the screen that KN filters and many other aftermarket products that claim more power actually work. We have also dynoed with NO air filter and even that didn't add power. MYTH BUSTED! KN filters use an oil that is saturated in a cotton cloth held if form by wire mesh. ALL cars with a mass air flow meter for the last 10 years or so can't use a KN filter without problems down the road. The oil eventually makes it way up to the air flow meter and the oil coats little tiny sensitive sensors. Plus the dirt that is not captured by the filter also coats the sensors. When this happens all sorts of problems can happen, from poor gas mileage to a no run situation. KN filters LIE big time on the HP gains and MPG gains its all BOGUS. KN filters ONLY belong on carburated cars and cars with mechanical mass air flow sensors. Some people say this oil in the MAS problem is related to people putting to much oil on/in the filter ALSO a busted myth. Car companies are always looking to get a better MPH and hp and torque rating if KN filters worked and didn't cause problems ALL cars would have a KN filter or similar filter brands in every new car built.
