I just installed these about an hour ago and I must say, I'm impressed. Better idling and a better WOT. I picked these up at NAPA but you can get these anywhere, just ask for 93 RX7 spark plugs. They cost me about $7 each (2 leading and 2 trailing). The length is a bit different, they are actually about a 1/2 longer than the RE9B/RE6C but that shouldn't be a problem.

 

did u put those plugs in your rx8? if so, then ima have to get some too

 

Yeah I have these in my RX8.

 

Been using them for about 9000 miles. They work great.

 

this is hilarious...

I put RX-8 Iridium Plugs in my 93 RX-7

 

and you probably notice better idling and increased top end

welcome to the world of psychosomatics.

 

No, welcome to the world of:

$6 a plug > $20+ a plug

 

or $80/plug if you live in the antipodies

 

i already posted on using the rx7 plugs... i've been doing it in customer cars for a few years.

only downside is they wear out faster.

*edit* only NOTICABLE downside...

 

how soon will they burn out?

 

depends on your driving, turbo or n/a, etc... 10k on one turbo car and counting.

 

So did you get the BUR-9EQp ( platinum)?
If not is there any different because it half price of platinum
Thanks

 

i'm running them with no issue.

I'm going to just change them every 12K. for $30, it still cheaper than changing the other plugs every 25K and your plugs are fresher.

 

i haven't noticed the platinum plugs lasting any longer than the standards.

i wish ngk made a bur10eq...everything the same as the rx7 plugs, just in a colder heat range. and then maybe iridium on top of it.

 

I am running the 9EQ L/T in my turbo non-plat. They seem fine to me =)

 

the cost-to-benefit...

they might last half as long, but they're 1/6 the price. that's 3x the value

 

plus tax, license and destination fee

 

Has anyone tried to put standard core plugs(eg BR8EQ ) in the leading and Irridium plugs ( bur9EQP ) in the trailing
Can we mix 'n match 'em

 

better idleing / increased top end was due solely to the fact that you replaced the plugs with fresh ones.

 

You mean Platinum , right ?

8's OEM plug use Iridium , the BR8EQP use Platinum.

 

oops my bad
Anyhow , has anyone mixed and matched them

 

just use the 7EQ/9EQ combo... you're probably going to foul out whatever plugs you've got anyway if you end up flooding

 

Which I did!! I was at school and my dad decided to move the car. I came back for the weekend and it was flooded. My method for un-flooding is so beast though

Time to get new ones, after what? 2 weeks.

Gheyyy

 

I can only find the bur9eq and the 7eq in platinum. Is running the platinums a problem if I have a turbo? And how much colder are these plugs from stock?

 

Anybody?
