rich[182]
For those who are thinking about getting a sealed IK, Below is link with pics to the CDA section of BMCs website as well as link to page with dyno results on a Mini Cooper S, bhp is roughly same to a 172 and it gained 6bhp, I know every car is different but assuming the 172 also gains 6bhp its good value for £160 (sure its available somewhere for this price inc club discount)
