NGK UR5's

[turboaddict2]

are these plugs the same heat range as the AC R43's or 42's?

I believe the same as the 42s. I have them in my GN, mostly stock, and thought they would be too cold but have had no problems at all. I have ran up to 22 lb boost on a stock turbo. Over that, which is pointless for me, I can not comment.

TurboJoeV6, Joe Reif, has done some dyno comparisons with these plugs with good results. May be able to find that on a search or contact him....OK, just found the post info I saved in a word file from a post on gnttype. I'll email it to you. Tim

thanks Tim. that was an interesting article and it sure convinced me to get the UR5's. So what store sells these? I only got a Pep Boys around my area.

I went to Pep Boys today to get the NGK's. THey have them. So I told the guy I wanted UR5's. He said the only start with B. Did I say the wrong number? Or am I supposed to say BUR5's?

UR5 is the correct part number as here's the stock listing.

I looked at all the NGK plugs at pep boys and they all started with a letter such as A, B, C, or D and then the part number

Pep boys here in N.Y didnt carry them either . I found them a West marine here dont know if you have that in Jersey but .....

UR5 is part number 2771 and UR6 is part number 7773.

Yes it's true, I picked up an honest 16 HP at the rear wheels by just switching from the CR42TS to the UR5's! Not to mention when tested in a spark plug tester, the NGK's had an almost 99% success rate over the AC's. The AC's spark almost always blew out or were sparking all over the plug itself when placed under very high pressures??? Out of a total of 12 AC's, only 3 passed the test. Out of the same amount of NGK's, I think only 1 failed....all test were done at the same gap and in a controlled environment. I put a set in my TTA and noticed an immediate improvement in idle and off idle acceleration. And to answer your question, the UR5's are the same heat range as the CR42's.

 

[turboaddict2]

Oh ok so I just gotta say 2771 and hopefully Pep Boys has them.

 

[turboaddict2]

Went to pep boys again and asked for the UR5's. Also said the part number 2771. They said they don't normally stock those plugs so I had to do a special order. Plugs were $3.65 each ! Is that the normal price you pay for those plugs?

[turboaddict2]

Does advanced auto parts have a website?

 

[fast eddie]

do a search on advanced auto parts or call the ones in your area

 

[fast eddie]

should you still run the same gap on the ngks or do they require a larger gap?
