I just bought a JRSC from a guy for my daily driver, i wanted a bit more pep but nothing crazy. Well i've always used good ole Denso orNGK plugs but just for shits and giggles i typed in performance plugs on google to see what i'd find. You get the usual Bosch platinums, Denso Iridiums amongst many other familiar brands. I saw a few that were new to me. There's the E3 which i have heard of but never really read much about. The Halo plug and the Pulstar plug. The Pulstar looks cool but for $25 bucks a plug there out of there minds. Anybody use or ever try any of these new plugs. Just curious to hear some testimonials. I'll probably stick with my realiable Denso's but it doesn't hurt to look around.
