I'm always looking for more HP for my car. What are your thoughts on this guys?

For $350 you get 8 peak hp, and those are Dinan numbers which are often referred to as, well, optimistic. :)

I would think of a MAF or headers first, and you can always have your throttle body bored out by a mechanic for less than that. Someone posted a link once... maybe on another board... of someone who did a good job at boring out the BMW TB's.

The air flow is a function of lots of parts along the way, so you have to make them all flow better to see much gain (weakest link kind of thing).

OTOH, probably won't hurt. Maybe you could get a dyno run before and after and let us know how much it really adds. Would be interesting to get independent numbers.

Personally I'm waiting for Mark to get around to offering the m30 MAF... I'm saving my X-mas money for that.

EDIT: I guess you already have the MAF then - so go for the headers!

I thought the M50 already has an MAF?
