No problem smile seems to me a lot of the cars I've seen could do with new ones!

Do all models use the same filter?

Ive just cleaned mine using the K&N Recharger kit. Gone from black (dirt) to their original red colour again. Still doing the job, but if I changed them I would want some slightly longer ones. Ive seen a Noble with Green Cotten versions that are much longer, picked up the airflow better but part blocked the intercooler

little point buying replacements as K&N's are designed to be fully cleanable and don't wear, stock items flow enough air for even mildly modded cars.

For a litte T25 or T28 to make in the region of 1.2Bar into our configuration I'd have expected the filters to flow enough for 500bhp Nobles.

If anyone is thinking their filters are past it then they should also be carefully inspecting the trunking hoses between filters and turbos. These can become brittle and crack & can rub causing air leaks and possibility of dirt ingress.

Good advice on the trunking! Also make sure the front turbo trunking doesn't have cable ties stabbing it from underneath, found this on mine and this was the reason the compressor wheel had been damaged. For such a cheap price on the filters it's not even worth cleaning them in my opinion as they are never as good as new, and from experience with other cars the paper can degrade over time. This is such an important performance factor too on dirty filters I'd lost 10 bhp.
