you know what's really interesting about the posted dyno is that it offers gains in hp/trq @ low rpms, too - unlike most aftermarket intakes.
an interesting comparison would be to see how well the knock-off fares against the boutique piece. if the actual filter elements are the same, the difference in performance would be the result of differences in details & quality of manufacture.

but, wouldn't that be an interesting comparison?

Your not running the stock diverter valves huh... If they came out with an intercooler upgrade i would buy it knowing right now that it will cost more than the Gruppe M intake, the point is that you need a larger intercooler for this car to put down more power. I was gonna pay VF engineering for a $15,000 supercharger for my V-8 S4 before i crashed it, i dont care about spending the money as long as i know that it is well spent.

Hate to bring back a dead thread, but just noticed the dyno is pretty choppy for being smoothed. What's going on there?

I have been running around for a few days now with the Gruppe M intake on my car. It is the only mod done thus far. Well the intake isn't really mine per say... but I might just keep it. Anyway the intake noise has increased a bit as expected. I can only really hear things with the windows down though. I would like to test out downpipes in combination with the intake next and also in combination with the stock intake.

I have never really encountered so many people who weight their modifications according to price versus amount of horsepower gain. I guess I have just been brought up in a much different area of the performance world. Personally I look at price according to quality of manufacturing and ability to perform the intended function.

The product in question here in an air intake. You can't expect more of it than any other product of the same function. There is no comparing air intakes to exhausts or ecu piggy backs. They all have different intended functions. You either want an intake or you don't want an intake.

Since interpolating the numbers on a dyno sheet can be annoying here are the exact gains at a few RPM points:
4900RPM: +12WHP/+13WTQ
5850RPM: +14WHP/+14WTQ
6750RPM: +16WHP/+12WTQ

The Gruppe M intake provided about a 6% hp gain. Anyone who might desire to achieve above a 10% gain with an air intake is a bit naive. The only car I have been able to gain a substantial amount of power (10%+) with only an air intake is the '05.5+ VW Jetta. If you have seen the stock intake system on that car is it extremely restrictive with many varying cross sectional areas (the intake runs through the engine cover...)
TOTALLY AGREE WITH YOU!!!
