speedyfix: magkano mag palinis ng plugs sa inyo? PM me naman details. Thanks.

Back to the topic: I'll stick with stock plugs, if ever may gains yung iridium/4 tipped plugs minimal lang siguro (Bought a set of Iridiums for my Adventure before pero bumalik din ako sa OEM laki kasi ng difference sa price). I'll just save the money and spend it on other things.
