First, thanks to everyone who helped me figure out the belt tensioner.

I still have the airbox off and was wondering if it is really worth installing a K&N air filter? K&N claims all kinds of good things as a result of fitting one of their filters. Does anyone have any practical experience? Does it really make any difference in performance?

Depends on what your running and power levels.

Standard 996tt has a good OEM filter. Once you start to tune then it is always recommended to put a more "free flowing " filter on. I have been using K&N filters since 1983. Firstly on my Hillman Hunter Holbay and every car since!!

They do make a difference, but IMO only if the car has been tuned to make use of the extra air flow.

I have had a K&N filter in a few cars in the past. I can't tell any difference in performance. I have also read other people's experience and it seems to have no observable benefit. There are some potential problems. If the filter is oiled too much, it can cause some warning lights to go off regarding the MAF. Not worth it.

Nothing wrong with either the K & N or the BMC filter. Like Sunnyside said they will work better on a car with mods to make use of the increased air flow. Especially a Turbocharged car. You will get more sound. As long as you follow the instructions with the filter (not over oiling) you wont have any problems with your MAF.

I have used them on my BMW's (back in the day) and all my Porsches and I have never had a problem.. Just my 2 cents..:rolleyes:
