Engine compartment temperatures on today’s’ vehicles are higher than ever. With hood seals, belly pans, air guides, and tight fitting power trains, the engine compartment doesn’t have the same empty space and airflow it once did. Factor in the high flow coolant fans moving radiator heat through the engine compartment and you’ve got enough heat to slow cook a pot roast. Using ambient air for engine consumption just makes sense; colder air is denser and can be matched with more fuel, which results in more power. Unfortunately many of the ‘cold air intake’ kits available today are merely a tube with a high flow filter on the end. While this is a step in the right direction major considerations are being overlooked that would maximize the gain. I started with my 850 and relocated the exterior temp sensor into my factory air box to do some baseline testing. Come to find out that air box temps would frequently exceed 120F even on a 70F ambient day. At speed the air box temps dropped to within 5F of ambient and after running (even at idle) for 5 or so minutes air box temps would drop to approx that same level. Running the new Ipd short ram intake I was able to keep airbox temps to within 2F of ambient although I still got high hot start temps just like with factory. The real benefit in a short ram intake is due to the more open element design of the filter and better breathing. Boost came in approx 400 RPM sooner and the dyno chart showed better power curve as the turbo spooled. This intake also shields the ignition coil from high under hood temps as well so using the ipd performance coil kit means better power and increased longevity! -Lucky Arnold See this item on the IPD Website.
