hey everyone, i need some help.
So i have CAI, upper cp, catless dp, turboxs fmic, trifecta selective tune, one is gms1, the other is set to 23psi. I just bought some ngk LTR5IX-11 gap .036 for my lnf. my issue is that when i stomp on the gas every once in a while the vehicle seems to bog out and sputter a little before taking off. im not sure if that because of my gapping or what? can anyone let me know if i need a colder plug or can i re gap this ones so i dont have to spend another 40+ bucks for a set. THANKS

I know your plugs are gapped to large, close them up to like .32. I ran some NGK plugs but they werent the ones you are running, I ended up putting the stock ones back in my car.

so .032 is for all plugs on a LNF or just these?

so i checked the gap of my spark plugs and it was @ .046 ....defenitely no where near .036 that the store told me they where pre gapped at...so im setting them to .035 and see how my car reacts, anybody else have any inputs on gapping??

well i just set them to .035 and the car seemed alot better, now im cuious to know if .032 would be better? but i dont want to close them to much and have an issue... what can happen if they are gapped too small as far as parts braking or having to replace something??

My car had a little hiccup in the higher boost range ....like 22-23 psi .... so Im sure i was getting some mild spark blow out. Reducing my gap took care of the issue and smoothed out my idle. If you car is running fine its not really worth the time to re gap the plugs ...... all cars are a little different so your might be happy there .

For instance.....my GM stageII SS/SC would break up real bad at full throttle with the stock gap (.039)....... It would seriously sputter and pop ...... I was shocked when dropping them to .035 fixed the issue ...... if I hadn't experienced it ......I prolly wouldn't believe tightening the gap could fix such an issue .

As long as your careful closing the gap there shouldnt be an issue . I've heard of the ground strap breaking on some plugs but Ive never had a problem. I think some people must really bend the crap out of the strap thus creating a crack or weakening it .... then it'll bounce around the cylinder until its spit out the exhaust lol

im still set @ .035, took it out last night and gave it a few hard stomps. it felt alot better than before but it still did it just a little, enough for me to notice it. so im going back in this morning and changing it to .032 and see how that goes
