Which one is better finally? Some people were saying that the lost power with the ITG in their coupes? Whats better for the 240 or 320?
Thanks

Don't know who said that but with a stock C230 coupe I lost .1 HP with K&N and gained 1 HP with ITG. With the additional boost from a pulley kit I got 3HP gain with K&N and slightly more with ITG. It's up to you but I doubt that in a stock C240 you will see much gains but I don't expect you will see any loss either. The factory filter will be changed for you at the 4 year/50K service. You may want to consider getting a factory filter earlier like at 2 years because it looks pretty dirty at that point and this way you won't lose power.

There was some guy that had a dyno of his C32 with the ITG the lost about 6HP from stock. Now I know a drop in filter isn't going to do much, but I dont want to lose power. I'm sure the results are differn't from the Kompressor engine's then the NA 240 and 320 engines.

I am using BMC on my C32 right now....I havent dyno'd it b4 and after but I am pretty sure the car feels smoother and stronger on high end. I will strongly recommend BMC.

I'm getting a couple of ITG & test them out this week. I shall post my feedback afterwards.

On a normally-aspirated motor, the gains from an air filter change are more dramatic - I felt like a sucker, but I bought and put K&N recently on mine and I was really surprised by the power gain. When the aspiration is manipulated by a turbo or supercharger, that manipulation is so great in comparison to the effects of a different air filter that the air filter change makes little, if any, difference....
