Can i upgrade the sparkplugs ?
 

I have a 94 camry v6 with 86,000 miles. Im planning on doing a minor tuneup soon and want the most power out of my engine. I keep hearing that it's always best to reinstall the original plugs, but i know that there are ones that will boost performance. Original or upgraded? And for upgraded any suggestions ?

Thanks :)

Stick with the stock plugs. This is your best bet. NGK plugs are also good. Ive always used them and never had problems. Its important that you know what metalic material its made of. Gold Platinum Iridium etc ..Make sure its the same or it could cause future problems.

the best ngk plugs are the iridium tipped laser plugs. they laser weld an iridium tip to the plug. thats where the name comes from.
