No. I did the Full Race intercooler, throttle body spacer, and TurboSmart BOV. It was nice. But great after I got it tuned!!!
The tuner simulated a CAI by opening my OEM air box. He told me when my Full Race CAI came I could throw it on. The truck accelerated like crazy after the tune. When I put the CAI on it ran like dog !!! I was a little pissed off to say the least. Threw the stock intake back on, and Voila!!!
Anyway… all that is just an example of why you need to get the vehicle tuned to get the FULL benefits of the money spent. And, have all parts on hand for the dyno!!!
Since you’re doing the downpipes you will see a sweet increase in power. Throttle body spacer, and intercooler, got me at 603lbs per foot of torque at the wheels in my Expedition. Can’t wait to get downpipes as well. Then, I’ll have to head back to the tuner for a third time!!! Crap!!!
