pulled off the silicone pipe from engine side one of the canisters today (from behine light) and found loads of dust in the bend. Clearly the unoiled filter isnt up to scratch in catching all the dust. maybe the MAF is screwed now. that might explain why the low values 180-210 g/s on recent logs. ....
trying to fit an oiled K&N conical filter in place of one the canisters is proving tricky, just due to its size , and the other canister in the way. will have to have a rethink this one....
