Hey, i have the larger flow MAF from SLP. It has a removalbe screen. Is it ok to remove that screen? Will it cause harm to the engine? Is it even worth the time of takeing the MAF out?

 

Not worth it.


FYI, I've been told by several engine builders that the stock MAF flows plenty for a 450+ hp engine.

 

I got it not just for the flow but the SLP larger MAF also advances your timing, i actually am getting about .1 better at the track too...and i got it for a good price on ebay.

 

i removed my screen and had it bored out bigger and polished...i used the stock one.....i notice the difference when it pulls near the top of second

 

I have an SLP MAF. Everyone I spoke with said to leave the screen in. You are already getting the advantage of the bigger bore and the screen actualy helps to straighten your air flow out.

I ran a ported/descreened stock MAF and had very lean conditions that caused detonation aroud 4500 RPM.

 

I installed ported MAF ends on my 01 Z28 A4, and then had the vehicle dyno tuned 1 week later, due to a TC change.

I was running very lean on the dyno, however the tuner was able to correct the condition.

UNLESS YOU ARE PLANNING TO HAVE THE VEHICLE DYNO TUNED, LEAVE THE MAF ALONE.
