I can't get NGK 6097's locally anymore (discontinued). Which plug would work best for BPU @17psi?

 

[Nick 95 6sp]

They changed the part number but that plug is still available under the new number. The old 6097 was a BKR7E-11 and the new version of that is now 5791; they're gapped 0.043" out of the box so you'll probably have to regap. Better double check that 5791 number though since I've never bought them since the p/n change since I switched to Iridiums.

Ngk 4644

perfect! I just looked that up and since it's a BKR7E gapped at 0.035" it's a better choice.

You still using those Denso? How did you like them? Reason I ask is because my GTE says the stock plugs are a funky double pronged PK20TR11 and I was thinking about just getting the IK20s since they are only like 70c extra a pop.

Yes, I'm still using Denso Iridiums...I think the price on Amazon is pretty good and they seem to last a very long time and they've never misfired yet.

Autozone carries 4644 at $2.49 each. I just picked up a dozen the other day. As mentioned above the stock gap is 0.35 so you'll need to gap them slightly.

I have them gapped at 30 and I've run them up to 31-32psi on C16.

Just called my local autozone and they said special order only on the 4644's

any other suggestion for plugs that arent iridiums for 11 bucks a pop?

how many PSI are ridiums plugs good for? i think right now i am running ngk 3330 plugs but i am sick of changing them every oil change..i am actually looking for plugs that can last longer

order online..


actually funny this thread popped up, i was tired of waiting for my order online, and i found out advance carried the 4644's, so i bought a set there..
get back home and i find a package on my doorstep (only been 4 days). and theres 2 sets of 4644's..... fuck now, 3 sets. and 1 going in.

rockauto.com has a great price for them, cheaper than advance (including shipping). like 13 for 6 (including shipping)

My local NAPA always has 4644's on the shelf.

 

[FLINTSTONESKID]

^^^i have my smallish local speedshop keep an extra 6 on hand at all times, they dont mind as they arent that pricey, and whenever im in a pinch, i know they are there for me

 

[RogueSupra]

My last set of NGK 6097's are in the SupraTT now... looks like I am going to get some NGK 4644's now... I will call around my local area 1st before I order online and see what the best deal is.

My NKH 3330's seem to be lasting pretty well gapped at .028 running 15psi with a DLI. Its got a SP74mm but it hasn't been ran hard with them. I just bought the high dollar Iridiums but haven't put them in yet. Hope it wasn't a waste of money?

 

[FLINTSTONESKID]

seems that iridiums have worked well for some and not so well for others, guess you will have to feel that out yourself. for me, they dont work.

 

[botchilah]

I use ordinary NGK BKR7E-11 with a gap of 0.028 inches / 0.7mm as per AEM's recommendation in their EFI BASICS document I downloaded. Cars runs really well. I do change it every oil change though.

 

[Tim1137]

Called advanced, they carry 6 on their shelf. I kinda feel like they are there just for me =)

gap for BPU cars should be 0.035 right?
