"The sound, the fit, and the appearance all meet expectations. My G35 jumps when I punch the gas. I couldn't be any happier. Thanks Injen and auto anything. Best price around and believe me I looked. Injen cold air intake can be turned into a short ram if needed" —Philip O from Lansdale, PA bought an Injen SP Series Cold Air Intake for a 2003 Infiniti G35, Coupe.
"Installation was pretty simple, got the intake with a $25 manufacturer rebate. As for rating I installled it with a kinetix velocity plenum so I cannot for say how much performace enhancement was added but Im sure it it was signficant looking at the stock intake and filter which looks very air restricting." —Steve N from Washington, DC bought an aFe Cold Air Intakes for a 2003 Infiniti G35, 3.5L V6.
"Great intake system. Very pleased with the result. Car sounds roughly the same up until ~2800 rpm then the engine gets much louder and there is an extra kick of power. The sound is fantastic- very throaty. Gas mileage has also improved about 2-3 mpg. Also extremely easy to install. Took about 30 minutes and I took my time." —Austin W from Tucson, AZ bought a K&N 69 Series Typhoon Intake Systems for a 2003 Infiniti G35, Sedan, 3.5L V6.
"Intake bolts on and looks great! product is very high quality. I noticed a much better sound when driving but the horsepower felt sluggish in 2nd abd 3rd gear in high RPMs. I was not to thrilled about that but the product was as promised and great company to work with!" —Anton B from Fort Wayne, IN bought an Injen SP Series Cold Air Intake for a 2003 Infiniti G35, Coupe.
"Overall a good product which is very helpful. I believe its a lil pricy for the size but worth the buy. I recommend for everyone that has a cold air intake." —Jose R from Emporia, KS bought an AEM Air Bypass Valve for a 2003 Infiniti G35.
