I'm still waiting to see results. Don't most people only install MSD ignitions on the leading plugs anyway? It seems logical.. I'd just hope that with this mod people are beefing up the 2 plugs to get optimal burn.. It makes sense, just baffles me that until now, it wasn't very highly discussed. Oh well. I'll be patient. https://www.nopistons.com/forums/pub...IR#>/smile.png

^^^exactely justin. Soon enough we shall see whether its wworth it or not...either was i woudl love to see some in depth testing!

Dudes buy a bolt and save $149. https://www.nopistons.com/forums/pub...1047683664.gif

if skip charged $400 for the plugs and gave you free tunning then i could see paying for that. but that is insane to pay for two bolts. even a $100 is crazy.

didnt post over there cause it would have just gotten buried but heres my $0.02



the pros:

it removes a potential hot spot, ie the spark plug

it also eliminates the split timing tuning variable



the cons:

you cant break the laws of physics, they work by lowering cylinder pressure by not burning completely/making as much power/lowering charge temps



will it pass smog? granted its easy to put the trailings back on



due to the leading plugs being on the same circuit, if you get into a potential flooding situation, you're screwed. in the stock system if one leading plug fouls neither fire, but if it starts on the trailings it will usually clear up. with the plugs you have no trailings, and you're screwed



the fact that BATMAN is endorsing it means that theres no chance of technical merit, he's the guy with the tornado air! we tried to get him to dyno it back to back with and without it and he wouldnt do it! he has NO dyno sheets, wont race anyone who can verify how fast his car is, or even let people ride in it.



and @$450 the markup is so huge it makes a former mazda parts manager blush! i'd be charging $49.99 or maybe $79.99, thats still a 1000% markup, those bolts cost $5 each TOPS.

If one fouls, the other will still fire - they are in series.



But I agree - it's not a real upgrade.

yeah im just curious who in the hell made that price up the US government? https://www.nopistons.com/forums/pub...R#>/bsflag.gif
