VCM OTR Intake (GT & GXP)

VCM’s over-the-radiator cold air intake kit offers huge horsepower gains by maximizing air flow with a straight ram-air design and massive K&N filter. Because air is pulled in over the radiator, it also feeds much cooler air into your engine than other intakes, resulting in even more horsepower gains. Molded from high-quality, OEM style molded plastic, VCM’s kits are some of the nicest on the market and are known for being mistaken as a factory part.

You can expect a gain of up to 20-30 HP with this intake over stock, and even more with a good tune.

Below is a dyno test video comparing the VCM OTR intake with various other brands. In this video, made by a shop in New Zealand, they were able to make an additional 29.5 crank HP over the factory intake and 55 crank HP with a tune. This dyno test was on a Holden Commodore (Australian version of the G8) with a full exhaust.

This new updated design features a revised PCV line setup that locates the PCV line after the MAF and eliminates the possibility of a lean code being thrown. The new injection molded housing separates for easy filter cleaning or replacement and features an airtight seal to prevent air flow and debris from bypassing the filter.

This kit can be installed with simple hand tools in about 45 minutes. The radiator must be tilted back very slightly and upper radiator mounting brackets are included to achieve the required angle. The intake can be used with aftermarket MAFs and throttle bodies, but may require aftermarket silicone couplers. We sell couplers that allow this kit to work with Magnuson superchargers. The intake can also be used in a MAF-less setup using our adapter kit, sold separately.

Note the difference in intake and filter size!

* MAF-Less version includes couplers required to eliminate the factory MAF and requires a custom speed-density tune.
