Review on π Spectre Performance SPE-9741 Intake Coupler - 4x3.5 inches, Black by Nicholas Harrington
Life saver when installing LS.
I bought this to install a MAF on a 4" intake manifold. Works great if you are replacing an LS with a hot rod and building your own air intake which is almost always needed. On LS engines, the throttle body is 4" in diameter, and on the 75mm MAF, both sides are 3.5" in diameter. For the 85mm MAF, one side is 3.625 inches and the other side is 4 inches. 85mm DMRV.
- Top marks for support and durability from testers
- Available in white only
