For plugs for a justacooper, I just recieved some iridium plugs pre-gapped to .032 Should that be ok for the regular cooper? I have noticed that all NGK plugs sold for the cooper NA are this gap.
..we have the single electrode and the factory like 4 prong that work well with the pullied cars. The single are better for cars with a head and bigger boost
jan, can you explain why? if a single electrode offers better combustion at say, 260 hp, why doesn't it also improve combustion at say, 205 hp?
