Q45 MAF adapter and BPI Velocity Stack $50

$50 shipped firm for an adapter to run a Q45 MAF, 1 coupler, and 3.5" BPI Velocity Stack.

Not looking to split this up at the moment.

No dibs. Money talks.

Info on getting a Q45 MAF to work with A32 wiring and a lightning MAF adapter. The MAF adapter for sale in this thread matches the ID of the Q45 MAF better.

Stupid question....but what's the inner diameter of the Q45 MAF? From the pic in your other thread it looks like you just used a completely unmodified Q45 MAF, instead of the Q45 MAF sensor in a big aftermarket MAF housing.

I take it you like the 4" setup more than the 3.5" setup? Any other reason why you're selling? Thanks!

I do like the 4" setup on my HR hybrid setup. I figured if a full 5.7 gen can see gains, my HR should as well.

I do think a 3.5" setup for a regular DE is plenty though. My 1/4 mile back half gains from going DE to HR were pretty significant. The HR heads/cam definitely flow a bit more.

With what I'm selling, the MAF adapter makes for a seamless transition from bell mouthed velocity stack inlet to MAF exit. My Lighting setup had a step down.
