The parts I received may be mis-matched from those in the manual for Coyote gen 3 install. FFR manual says to get the Treadstone 4" MAF pipe, but the Coyote gen 3 throttle body, 90 degree rubber hose and air filters provided are all 3.5" pieces.... Not sure how they got this wrong, but I'm just going to order a 3.5" treadstone MAF tube to remedy the problem....
