what are you finding to give the best result on MAF reading, some sort of air intake system like EVOMS, or simply a K&N filter and swiss cheesed airbox? This all being on a 1.8T as well.

I used to have an A4 1.8t and I used a EVOMS intake but now I am helping some friends in the tuning of their A4's and I'm curious if anyone has any data regarding this as to which actually benefits more. Any tips would be awesome. I am going out now to run some logs on it, stock other than a GIAC chip.

Others (oiled ones) are known to fry MAF's, and yield little if ANY gains. I have HKS intake on mine (previous owner) and I hate it. leave it be, the airbox/intake is one thing Audi got right the first time.

If I get the chance, I will log MAF on a few different intake setups and post the results.

203g/s with a K04 + stock exhaust + stock SMIC

up from about 193g/s with a purely stock airbox.

The computer in my old car did not like it when you removed the screen.... Wondering what the effect is with these cars.

Also....you think a K03 flows enough to see any MAF flow gains w/your air box gains?

screen |= Flow Straightener. As long as the FS is intact..you're all good

I put a cheap Fram air filter in and my car has never run better
