10% Mail in Rebate after your purchase of a CFM+ intake manifold.Offer valid August 1 - September 30, 2012. Don't forget to download the rebate form after purchase.
Regardless of which tuner, air filter, exhaust system or aftermarket intake you may already have, you need to dramatically increase your air flow. No other aftermarket intake comes close. Bottom line is CFM + does not make tuners, air filters or exhaust systems. But what they do is engineer, design and manufacture the ultimate intake for the Cummins and Powerstroke diesels.
