my car= mk1 punto 55 sx 1108cc.
i want to buy an induction kit! i have whittled it down to 2 (within my current 'i want it now' budget!), they are the usual K&N 57i & the rarely mentioned 'Raid induction kit'. Does anybody have any idea what i better??? aso if possible any technical info i.e. bhp increase etc. any help will be gratefully received.

Either kit will give you about 2bhp more than you have now. Get whatever's cheapest/sounds best.
