After much testing, brainstorming, research, and data review. We found the best intercooler for your X3! While testing in Lucas Oil Short Course Series, BITD Series, the Baja 1000 and several other off-road series, we have found the coolest performing intercooler available!
First off, C&R is an industry leader in cooling solutions dating back to the 80s. They supply much of Indy Car, Formula 1, Nascar, V8 Supercar, and many Off Road series. With roots in Australian off-road competition and Safari competitions they know exactly what we demand.
The best intercooler on the market today tested by us on the dyno and on track at pro level short course is now available from WSRD. The ability to maintain and control charge temps in turbo applications is critical for power and reliability especially when using or limited to lower octane. C&R implemented a core they developed for Formula 1 to use on the Can-Am X3 platform as natural airflow is sacrificed for packaging (intercooler top mounted horizontal in rear of car). A tube and fin core design offers lightweight, efficient heat transfer with much less physical size, and high flow.
We have tested the best bar and plate core from Garrett in a much larger footprint (12"x10"x4.5"), which requires mounting the core higher in the bed and modifying the intake cover. Not a perfect bolt on affair, but this angle does promote more airflow over and through the core. The C&R core measures at 10x10x2.67 which conveniently mounts in the stock location without modification. In testing we did mount the intercooler at a more steep angle to help natural airflow.
