My S2 is still a 1.6cvh is running 25psi of boost and is making 250bhp. Which plugs will be the best bet for this application as the current set of NGK 9's are past their best. Not really preppared to spend daft money on plugs but want the best sensible option possible.
there bloody good! Had them in since the rebuild and not failed once! Got a set of Champions sitting in the car just in case though. I think they are the recommended plugs for 'high spec' cvh's and cost about £25.
ur best bet to get r the ford 701 plugs work a treat on mine and only 12 pounds i had the ngk in mine but were no good for 260bhp it kept on blowing the spark out on boost
champion C57's or if you want to spalsh out, get a set of Denso iridium racing plugs (IK01-27), they are exactly the same spec / heat range as an NGK9 and work very well on my car (running over 200bhp with 22psi)
