I currently have a Euro HFM and airbox on my M3. I've considered changing to a CAI, but I have never seen any dyno charts directly comparing the a Euro airbox to a CAI. Comparing a US HFM and airbox to a Euro HFM and CAI is definately not the same test.
What gives? Does any one have the numbers?
: The problem with the kit you guys have is the euro air box. It does not flow any better than the stock air box...complete waste!
: Adding a CAI will make a HUGE improvement to your car. The hfm and chip work well in letting in more air and calibrating it with the correct fuel and air mixtures, but a shielded intake really enhances it. On the dyno you can expect...
: AA has seen about 24hp at the rear wheels
: ECIS has seen 21-23hp at the rear wheels
: Jim C has seen 24-28hp at the rear wheels
: Go with one of these kits, you will be amazed...

: : know how much more HP it would give us? I was

: : might add 2-3 hp, but weren't sure.
