K&N Jets

[carnage501]

Do you have to change the jet if you were to upgrade to a K&N bolt on filter for a 1.4 SR carb, if so what size jet and where do you get one from, ive only got the filter. :!:

nah, not for my money you dont. if u want to find out take it to a rolling road and they will tell you. but to be honest, i wouldnt bother. i aint really sure you can change the pierberg jets for anything else anyway.

but generally a bolt on filter is actually worse for ur engine than a std airbox on the 1400sr.
