Those prices are outrageous. Go to your local auto store and get part number 4177. Shouldn't be more than $16.00 and no shipping.

I am installing TR6 plugs today in preparation for my procharger, possibly next week. I did search about them and it looks like the best gap is .044. I will drive the car some before it goes into the shop.

I think this topic has been discussed plenty. I will record my experiences here.

that is a good gap for a n/a setup.

a P/a setup ive always gapped them at .032...................

ASH302 · 02-14-2010, 01:01 PM

you know we should just make this a sticky since this is basic the plug to use on a p/a or n/a. its a good plug to use and just make it a sticky

DSPTurtle · 02-14-2010, 01:53 PM

If you gap them a .044 you will have ignition break up. .032 is definitely the best answer for FI.
As for it being the best plug... not sure that is really true. Think about the n/a guys that only want to change their plugs every 100,000 miles... they need to go platinum. More of a stock replacement part.
Not everyone out there is like us gearheads that don't mind changing plugs every other oil change

toad · 02-14-2010, 02:32 PM

It's hell being old. I pulled the old and replaced them with TR6 gapped at .042 the plugs I pulled out were TR6 gapped at .035.

So I guess I need to pull them and regap them before it goes in for the Procharger.

I should have come in from the garage and looked at your responses - doH

funny thing - I don't remember putting TR6s in. I thought I was still running thr TR55IX.

sorry guess your right on that one, most guys that are going to ask bout the plug are more the guys adding stuff to there mach, so that is why i figured that. my bad on not thinking outside the box on that. i still think this should be a sticky that way it is easy to be found and also a question that gets ask a lot

systemdz · 01-30-2011, 04:18 PM

I just went to oreily's and they was telling me their computer called for NGK TR55ix iridiums. My car had Bosch fusions and it has a little miss if I hold it at 2000rpms. The plugs look old so I'm going to change them and hope it fixes my problems. My car is just basic bolt ons and I'm not sure which plug to get??? Any suggestions. Should I just se the autolites or get iridiums?

2k4mach · 01-30-2011, 05:03 PM

tr55ix are fine for you

systemdz · 04-13-2011, 07:17 AM

I just went through the same thing. The reason they "won't fit our car's" is because they are a colder heat range than factory. They will fit but if your running n/a you wouldn't need colder.
