After alot of research, I finally purchased a filter for our Late Model and could not be happier. We ran paper filters before and had to run grease on the cleaner and it seemed dirt still made it through. Now with the R2C filter we do not have to mess with the grease and our carb is cleaner. We will now buy one for our modified.

Infiniti G37 Cold Air Intake



R2C's Infiniti G37, Q50, Q60, 370Z and G35 dual cold air intake systems provide:

  • An unsurpassed finishing process option that provides a luster and depth unmatched by any competitive system or process. Black nickel is a show quality plating processes. While expensive to produce, no polished cold air intake can deliver the discriminate and high quality appearance that the G/Q/ platforms deserve.
  • No annoying hiss as experienced using competitive systems and gauze filters at part throttle. R2C performance intake systems are discreet and docile for comfortable cruise noise levels but deliver a deep, powerful resonance when high performance acceleration is demanded.
  • Excellent horsepower production beginning at a much lower RPM and maintained thru redline along with unmatched engine protection provided by the premium, military bred, R2C high loft synthetic media. R2C filter media is unlike other dry synthetics in design and structure and leads in every category of measured performance. No filter made today can provide the low restriction performance as miles accumulate and the filters begin to collect the dust they're designed to stop and hold. Plus, NO Oiling and  maintenance is simple. R2C air filters will last as long as you own the car and don't require a penny in maintenance costs. Saves time and money.
  • Easy to install with simple hand tools and NO Cutting of your G/Q is required!  Get yours today.
