"After our first driving impression, the manufacturers' claim of 20hp & 25lb/ft torque improvement over stock seems like a very realistic figure."
The website proclaims

Its for a e46 330i.

what gets me is these companies have plenty of money to actually dyno a car to prove their products but they dont. snake oil.

I would expect a horse power increase like that to only come from a serious modification.....like chrome valve stem covers.

[bahnstormer]

it could be 20hp at the flywheel below sealevel =]

they pull any number out of their arse and make it sound as fact

I agree with Kristian. It's all ********. We dino tested my 535 set up with a 20 cm long open K&N filter and 44 cm long one and compared this to the factory set up. The only increase was 3 bhp when reving it up, and at full throttle it even lost 5 bhp due to the hot air it was sucking up from the engine bay. Standard is better unless you're running a full turbo set up. The 44 sm filter sounded fantastic though, it sure gives the impression of going faster....

your just right man, like ive said before, ive seen
dyno testing, and with cold air intake-filters you
can realise 1 to 1.5bhp increase, maybe more on
a M30, but that is all we are talking about, but
keep in mind if you have a cold air intake at night
or on a cold day that figure might increase slightly,
like the old rule of thumb, a 10 degreeC drop in
intake temps will increase crankBHP by somewhere
around 1%, so you could be looking at a 5bhp increase
on a cold day........................every little helps i suppose????????

Ha,ha,sorry mate, It´s already got a new home, on the airbox I´m attempting to make for my ´76 twin Weber 16 Manta. They are not expensive at all as it is a universal fit filter. It cost me approx 85 dollars here in europe. Guess it would be cheaper over in the US.
