hi there.
i have just got rid of the hks style mushroom filter and iam goin to re place it with the standard air box unit with a performance fillter....
was just wundering if its worth smoothing out the air box on the in side ... to allow better flow.

i done this on my mk4 golf turbo but also added a better feed in and the results were there for not alot of work.. and it also keep the standard look under the bonnet.

 

i dont know about smoothing, but i have been told to get rid of the hks green mushroom, and replace with standard air box and performance filter... thats because my car is hesistant, and the maf sensor is going haywire because of the hks filter...

 

i got a hks musroom filter on mine never had any problem with it,im running 350 horse

 

same here ..... ill give the standard unit a try and see how things go .

 

i think my hks filter could of had its day anyways lol looks very old.
