[DSB335d]

This kid I know with a speed3 was telling me about how his tuner is recommending for him to get one for his intake. Something about better a/f ratios with this little piece installed inside his MAF sensor.

Anyone able to shed light on this? Not sure if this is BS or actually beneficial when tuning.

Made me think of that "tornado air" thing that I used to see advertised on TV and magazines... Lol
