Yes, the C7 Corvette Z06’s 6.2L supercharged LT4 engine makes serious horsepower … but who wouldn’t like more? How about 45 more horsepower and 38 more lb-ft of torque at the wheels? OK, you can drop your hands now.

Holley Performance Products is taking a “clean sheet” approach to intake design with their new iNTECH lineup of cold-air intakes for modern performance cars. Their intake for the 2015-’17 Corvette Z06 is an impressive bit of kit. It installs in just a few minutes with OEM-quality fit and finish. No other modifications are required … just plug-and-play.

The iNTECH intake is centered around an oil-free, four-layer, conical air filter that seals to the intake tube and airbox with a patent-pending “slip seal interface.” No more large clamps to come loose! The system uses the factory mounting points and blends in perfectly with the OEM engine components.

To sample the intake for ourselves, we traveled to Holley’s Bowling Green, Kentucky, facility to photograph the installation of the iNTECH intake on a blazing-red Corvette Z06. The installation took under an hour and the dyno results speak for themselves.

Follow along as we show you how it’s done. Vette

1. The Holley iNTECH cold-air intake for the 2015-’17 Corvette Z06 was designed using a “clean sheet” approach. It utilizes factory mounting points and features a patent-pending “slip seal” junction to connect a high-flow, four-layer air filter to the filter housing and intake tube.
