UR 5

[atgooth]

Guys I just installed a set of UR5 and they are working great. Boost is solid and no missing. Thanks BG your were right again. BTW I bought the plugs at NAPA .Cost 2.29.

Just what I needed to hear, I have a set and I am going to install them this weekend.

I will be doing this very soon as well.

For stock heads are the UR5 or UR6's going to be a better match? I think I remember UR6's for the Vortecs.

Stock heads - UR5 and UR6 fit, just that 5 is stock heat range, 6 is colder.

Vortecs - TR5 and TR6, same thing.. 5 and 6 are heat range.

what about the L-35's that were with McCoy engines?

 

[smeagol]

L35's use the same type of plugs as a stock head.

My truck loves the UR6s! I'll never go back to Delco plugs.

i just ordered those ur5ix plugs. I can't find any info on here about gapping them. They come delivered at .035.

They recommend you don't gap them. They come pre-gapped for most apps.
You can try to gap them, but be very careful as the Iridium electrode is small & fragile.

I'd try them @ .035 first, then see if you need to gap smaller.

How do youy know if you have to gap smaller and to what size? Sorry still learning....

You have to get a feeler gage. Pep Boys, Auto Zone etc. will have one. But the AC's I have gotten have all been correct out of the box. The NGK's are not adjustable.

If you were having a miss at high boost you would probably gap them a tad smaller. Maybe .032.

But, like I said earlier, they're fragile and you run the risk of damaging the electrode if you try to gap it.

I believe the NGK UR5/UR6/TR5/TR6 can be gapped, but their IX Iridium equivalents aren't supposed to be.
