K & N air induction problem, please help!
hi guys, i recently fitted a K & N 57i kit to my 156 2.0 ts, 99V, and initially on test drive i thought it a worthwhile mod. I only did it actually because of the original air box lid screws and fixing being broke and were currently held together with a mixture of woodscrews and tie raps! so i thought the K & N would be a nice addition and do away with the old airbox altogether.
anyway, my test route was a rural one, and so out in the open air, always on the move, but as soon as i used it in traffic and the engine bay got warmer the car started to bog very very badly, leaving me at a standstill at some lights and an island on more than one occasion.
It still ran, and i had to coax the revs right up to get movment again, and i strongly suspect that this is due to the position of the filter, being fitted directly to the maf high up in the bay, it simply gets hot air from the surrounding space, no cold air from the outside whatsoever.
the kit did come with some flexi hose which is supposed to direct the air from outside to the located area of the filter, and this was used but to no avail.
the maf is brand new by the way and so should eliminate any worries about that being at fault.
ive currently put the induction hose back on the maf, grafted the cone filter onto the end of it, and have it suspended in the original airbox to at least get the cooler outside air that the original pipework dragged in, and exquisitely sealed the top of the box with duck tape!
i can let the car heat right up until the fan comes in at around 90, and still pull off pretty much as normal so i think this kinda proves the fault, but surely this isn't how it should be?
K & N are a trusted brand and ive used many of their products before, but looking at the design of this kit i can't believe it would ever work located so high in the engine bay, and directly surrounded by hot air!
so has anyone else experienced this, and more importantly how can i use the filter ive bought more effectively?
thanks for any comments help or advice you can offer.
