Add up to 30+ wheel horsepower to your C7 Corvette with this replacement drop in air filter!

After racking up thousands of miles on an ill-fitting and visually unappealing aftermarket C7 intake we decided there had to be a better way. Careful review showed the factory air intake piping and MAF housing outflow aftermarket piping, but the factory filter and how it mates to the factory MAF housing creates a significant restriction.

To address this problem with the factory filter we designed a replacement filter that has a thinner and less restrictive base to better mate up to the factory MAF housing, kept the filter DRY to avoid possible MAF oil contamination, and using a flow bench optimized the filter material, pleats, and other dimensions for maximum performance and filtration. See our dry filter material ISO 5011 testing here.

The net result was a drop in filter that offers 15% less restriction than factory and 10% less restriction than the "leading" aftermarket drop in filter, when flow tested through the factory intake piping. Back to back dyno testing against the stock filter and an aftermarket intake verified the same or improved performance levels when keeping all other variables (air/fuel, timing, starting temps) consistent.

Note the stock airbox with the BMS drop in filter performs the same or better than the revised GM intake with clear window (part 84152141) so if you are running the BMS drop you'll gain no power and might lose power switching to the revised GM intake.

Note for those already running the GM Performance Cold Air "Windowed" Intake we've recently developed a special version of the BMS drop in specially for that airbox.

The BMS air intake filter upgrade works with all year C7 Corvettes. 2014, 2015, 2016, 2017, 2018, 2019 with no modification.
