Thanks for you guys' help before with helping me choose the correct pulley size, im going to be putting in new plugs very soon. I have taylor 8mm wires, with a 2 1/2 catless down pipe, p-log and glasspack. Im going to be running my stock 3.8 pulley for a little while but im soon going to be dropping down to a 3.6 one i get a aeroforce interceptor gauge. So what plugs should i get? mine are pretty beat now so i dont wanna wait to replace them once i get the 3.6. If its possible id like to use the same plugs for both to avoid having to change the plugs twice, any advice would be greatly appreciated.
