So pi**ed off got up 4 o'clock this morning to search the net and found this thread and by 5 o'clock the airbox mod had been done and a filter on order off eBay.

Since then have done a 300 mile trip today, just with the airbox mod and what a difference!! Not absolutely perfect but getting close. Perhaps the K & N filter will do that.

Thanks to all.

I have the 1.8 and feel it is dead between 1st and second, which air filter do i need and can i remove some part of the air filter mine is the vvti i think.

Cheers Andy

you can take out the plastic trim in the sir box.. And if you want, you can replace with a k&n panel filter!

just been out and done this now, took 5 minutes, literally.

I think the 'placebo' effect takes place, but i think theres a slight difference in pick up.

done this on my 2.2dti today and it made a good difference power is available higher up the rev range now and does not dye off at 3k

where is the best place to buy a k&n filter from?

How does a filter stand on insurance, is it a mod or just a like for like part replacement? Is there anychance they wouldn't payout if something happened?
