New to Corvette Forum
 

Hey All,
New to the Corvette Forum; Look forward to being part of community. Just picked up a 2016 C7Z06 M7 back in October, going to be installing Kooks long tubes to kooks catless x-pipe to factory mufflers this weekend. Also installing NGK LTR71X-11 plugs. Any pointers would be helpful.

Cheers!

Congrats and welcome aboard!

Welcome, but I'm going to move this over to the C7 Tech/Performance section to allow for some of the members there to help you with the guidance you seek.

Congrats on your new ride and welcome to CorvetteForum.

Hello and welcome to the forums!

For your plugs, check the gapping. I’d recommend going with a gap of 0.038”.

Uhoh, I'm probably going to get flamed for that...

Copy that,

Thank you.

Copy that,

My tuner is LT1Z, advised the same gap specs.

Thanks FYREANT,
MY tuner recommended NGK LTR7IX-11 plugs. I'm currently installing 2" kooks long tubes to kooks catless x-pipe to factory muffler and AFE CAI and will be doing a 50% E85 tune fore my initial round mods, but plan on going pulleys/cam and cooling mods in the future. How would I gap these plugs as these do not appear to be (adjustable) other than torque specs? Am I missing something here? Sorry for the noob question, but want to do this right. Thanks.

If you are going to be adding more boost (pulleys) then I would drop the gap down to .032” or so. The plugs you were recommended are correct. Other option is to go to Brisk plugs. I would stick with the NGK’s unless you have issues with the boost blowing them out. You have to be very careful when gapping to not damage the iridium tips.

FYERANT I'm tracking on the above. What are the procedures for "Gapping" the spark plugs? Thank you.

I personally tap the end of them on the ground -VERY- carefully to tighten the gap. Do NOT put anything in between the plug tip and the electrode! If you tighten the gap too much, you have to Bend the top back a lil without damaging the iridium tip.

I only do it this way because I have done it so many times I have a good feel for how much force needed to get it just right.

Ahhh I see,

I'm thinking a feeler gauge and gently manipulate it down to said clearance would be the best way, but then again, you said do not damage iridium or put any object between the tip and the electrode. Should make for a tedious/interesting task. I'm sure I'll figure something out. Thanks for your feedback.

You can put a spark plug gapper between it to -check- clearance, just dont use it to try and bend the gap out.

If you need those NGK plugs we can get it for you!

Hey Josh I already have the plugs, thanks though, I just gapped them and have them installed already.
