So ive been looking around for some high performance spark plugs for the Mazda 3 2.3L 16 valve engine...

I heard of these plugs called "e3 spark plugs" but they dont seen to make plugs that fit for this engine... ive look around at Autolite, Champion, and Splitfire and there are just so many brands and plugs i dont know what to choose...

anybody got any advise???

There is actually a group buy going on what are called Pulse Plugs at the mazda3 forums. Here is the link to the post http://www.mazda3forums.com/index.php?topic=101671.0

dont bother with the e3 or the split fire your best option is to go with an iriduim plug from denso or ngk they make the best blugs for imports autolite and champion are good for american cars bosch is good for german cars. The dimond or split fire are only good becouse its hard to foul them out. If you are looking for a larger spark denso u groove is the way to go. if you whant a cooler spark go with an iridium plug from denso or ngk
