Shop now for air intake systems and air filters for your 2003-2007 Ram 24v Cummins 5.9L Commonrail Diesel Engine. This is the most popular upgrade for any diesel truck because making diesel power starts with taking away the restrictive oem filter housings and tubes and letting that beast breath! CPP offers air intake systems and high flow air filters and tubes from all of the top manufacturers in the diesel business including AFE, AEM, Airaid, K&N, S&B, Banks, Volant, and more!

We also offer stock filter replacements in washable wet filters as well as dry filter media materials for those who want to keep the stock housing because they are not doing major upgrades. Yes, we thought of you too! For maximum protection, look at our full line of prefilters to help prolong the filter life for dusty situations.
