Hey guys,

I'm running a Comptech SC on a MY04 and looking into replacing my spark plugs.

I received a recommendation to change it to the NGK 7173 .034mm and understand that it needs to be properly gapped.

I'm new to FI (and S2k for that matter...) and did the search but:

Is there a proper gap spec for comptech SC?

What does it mean when a spark plug needs to be "a step colder"?

Do I need to gap my own spark plugs? If so, what kind of tool do I need?

Sorry for the newbie questions...thanks!

what plugs would last longer than every oil change? recommend for FI that is...

 

Read this post There is some great info in that post and should answer most all your questions

 

I have the 7173's gapped to .034 as well.

 

thanks guys! Simply

 

Didn't I already answer all those questions for you?

Get the spark plug gapper at an autoparts store. Be careful to not touch the element too much when testing the gap.

you actually did, I was just a bit confused of what it meant until I read the thread on spark plugs.

Thanks Tim!

 

afrsyl,VegaS2k change out his plugs recently and also has the comptech.you might want to ask him to help you install them...I'm sure he picked up a gappin' tool.I need to change mine out aswell.



peace

whoa!!!! from reading some of those guys change their plugs out at every oil change!!?? is that overkill or this a maintenance issue with going fi??
