I have been running the NGK BUR7EA-11...for a few years now, I went to get a new set of those for my new motor and was told ,that number is no longer available and is replaced by GR4GP...which is a platinum tip plug(tiny tip) plug. when compared the two plugs seem the same( except for the obvious end) ...however there is a very slight length difference (slightly less than 1/16 )...has anyone used these plugs and if so...how did they perform. I did have them in the car...but was working starting issues out at the time, so the car did not run with theses plugs in it. thanks for the imput.

NGK 7031 (BUR7EA-11)....They are still available....

Look for "NGK 7031" on Rockauto...

$1.86/each....



EDIT: Also, Amazon has a pack of 4 for $11.56 so $2.89/each and plenty available...

I had this same thing happen at Oreilly's a few months ago. They had to order them and once they came in they were the ones you got. They said "our computer tells us that these are the replacements for those types of plugs". I just went ahead and ordered them on rock auto like Prelude said.

that would irritate me....If I ask for 7031, that's what I want...dont give me a replacement plug..especially if I have to wait on it...

Had to wait 4 days since it was Friday after 5 pm. Then after going on the following Tuesday they tried to play that BS.... This is what they've changed the plugs to is what the guy kept saying.
Anyway, good luck dude. Don't let them try to convince you these plugs no longer exist

I was also doing some reading on a forced induction site and they were stating that those platinum plugs with the tiny tip " do not have enough surface area for higher boosted engines" and spark blow out is most likely going to happen. that is always a concern for boosted engines especially turbo setups...cause we generally run more boost than a supercharged engine.

I have been looking at those e3's and was curious if anyone had ran them. My main concern was with the gap on the ones I was looking at and what it is set at since it's a fully enclosed tip

BR8es is what I replaced the 7ís with after experimenting with the god awful E3. Anything over normal 10-12psi and they are not boost friendly. Went with 8ís after 7ís fouled. My own fault mind you. 22-25psi smooth thru the rpm range.
