Gents, in preparation for fitting the Hybrid I/C I've bought from Judge, I've replaced my K+N Panel Filter (in standard box, but all pipework from box upstream (away from maf) was already removed) with the K+N 57i kit.

All seems OK, the AFR is showing blue on WOT and the car seems, if anything, to pick up slightly more quickly -

However, when listening closely to the filter (ear to it) after my test run, I can hear an occassional (3 or 4 per second) pock noises - sounds like a plastic valve closing - These are extremely quite - can't hear it unless you concentrate on it....

Maybe this is normal, but I didn't notice it with the panel - Anyone any ideas ?

Thanks,

Mark
