i tried to buy NGK Iridiums from Autozone (their website said availabe online or special order for store pickup)... then 5 days later i get an e-mail that they're discontinued!?

Amazon.com says in stock and "ships from and sold by" them as well, so i'll give it a shot.

Where do you guys buy them from usually?

 

got my **** on ebay. 13 shipped iirc.

 

for iridium??? i just paid $30 shipped on amazon

 

the same ones everyone else has: bkr7e or whatever it is.

 

Have you had good luck with the iridiums?? I gave up on the platinum plugs in my car a few years back; I seemed to get better spark under boost with the plain copper NGKs gapped tight. At about $12/set, I just change them every year.

 

BKR7E x 0.030" gap = win for $2-3 each

 

Iridium 7 heatrange like 7 dollar a piece on Amazon, golden pieces they are...

 

i'm sure the bkr7e's are just as good as the bkr7eix's (iridium), but i figure it's a small actual difference in price, and if they last longer i'm happy.

as far as having good luck with them, hard to say.. i've done a lot of incremental things since getting the last set of iridiums so during the troubleshooting process i'm sure theyve taken their fair share of abuse (running too rich for a while,then too lean, then cranking for extend period w/o starting, repeat).

This.

I tried all the fancy plugs, even Densos a while back, and nothing was as consistent as regular old NGKs. This has been true with every Japanese car I've owned.

 

lol @ gospeed81 -- you must be pretty good at that by now.. how long does it take you, 10 minutes?

 

Less. I have the COPS on a hold down bracket so it all comes up as a unit, 3 10mm valve cover screws and then in with the spark plug socket.

Plugs are cheap, and the cheap ones work. Easiest way to know what's going on in your motor, and keep it firing well all in one.

 

According to my shitty keyring gauge, the brk7e comes gapped at .030 out of the box. Do you all see that too?

 

That was the reply from the NGK rep.


They come pregapped between .030 and .034 I believe.
Most of us without COPs or some other stronger coil have to close that down to more like .025-.028.

 

I have an old system3 begi kit with ihi turbo running 10lbs. I'm not really sure if this kit has stock or upgraded coils. what gap should i run on the Bkr7e's?

Thanks

If you have problems go to .25

 

What do you all use for gapping? All that I have is one of these crappy discs. It sucks.

 

i use feeler gauges

 

Me too

 

+1 on feeler gauges.

 

Ive been running .035 on my bk7re's for about a month now on 10psi and stock ignition no problems.
