Backwards. BPR6ES if near stock, BPR7ES on higher boost. The experts run high power on 8's or 9's.

I hate people that just say SEARCH........but SEARCH and don't tell me typing in "spark plugs" doesn't give you 30 of these topics.

I realize you replied with an answer, but just because there is an answer with your post, doesnt mean you dont have to follow the rules.

It's really disturbing when people see the search box and a site AS LARGE AS this one and just don't use the tool.

starting to raise the boost a little bit and as wondering when the is it best to change the plugs to a "colder" plug, like the NGK BPR7ES. My dad has a set of NGK BP7ES laying around on his shop table, would those work or do i have to have the BPR's. thanks.

 

[Defiant]

The "R" is for resistor, to help cut radio interference.

Might as well see if your driving supports the 7s, I guess.

 

[Lord Khan]

I have 112,000 miles on my 97 GS-T, and I've been idling kind of rough lately cause I needed a tuneup. Well, I changed my oil, and put these plugs in, but they were $36 from my speed shop. Thats a bit expensive, and I'm just wondering what you guys that use them think of them? They were the recommended plugs from the shop for my modded DSM as they burn 1 range colder etc.


BTW, after installing them, car idle's very well now, and the ride is smooooooth.

 

[Black95TSIawd]

its just a spark plug. running one range colder is necassary if your running big boost. * > 16psi. Glad ur motor is running smoother though.

 

[Lord Khan]

Yeah, I keep my boost at 16psi anyway. These things were expensive as hell. Then I go to NGK's website today and see them for $2 per plug cheaper. Oh well, I'm happy though.

 

[CanadianTSi]

WOW I paid 10 dollars canadian for my NGK's...and they work just fine.

Did you get the same model NGK's? These are supposed to be their more higher end plugs. Even on the NGK sight their almost $7 a piece.

 

[Defiant]

The iridium plugs are mostly for hard-to-reach applications, where keeping the plugs in for a long time is worth the cost. Kind of pointless on the DSM, where the plugs are nice and accessible. But using them won't hurt anything.

Does anyone run the factory-spec BPR6EKN dual-electrode plugs?

 

[TD05HTalon]

I have the iridium plugs in my 2G and have had them for about a year and a half. they work really well and don't foul up like standard ones did. Mine cost $24 for the set though.

I do. I get them from Mitsu at $2.50 ea CDN (that's like $0.50 US ). Car doesn't idle as smooth as it did with the NGK iridiums that I used to run but they are cheap and seem to get the job done.

 

[Skunked tsi]

How about some Ngk Bpr7es that is what I run in my car you can get a set for under 8 us dollars. Also as far as i Know the number is the heat range and the number you have provided is a 6 which is the stock heat range. Unless there is something about the iridium i dont know maybe they run a step colder? I am unsure about that, 40 bucks for a set of plugs seems kinda steep to me. Thats just me though.

No, I run BR7ES's and they work just fine at 20psi...

 

[Lord Khan]

Here's a pic of the NGK BPR6EIX Extreme's. Apparently Iridium is way stronger than platinum, and their suppose to last a longer time. Also, they have a very thin electrode. Isn't that supposed to make a very good spark for better performance?

i run bpr7es's and change them everytime i run race gas or when the car just doesnt feel like it used to. They are cheap, and plugs are easy to change.

 

[98spydert]

I run stockers, there only about 9$ a box (4) at autozone around the corner from me... and thanks for posting this thread! You reminded me to change my plugs .

I have heard that under high boost pressures +20 psi, the little electrode can break off. I'm not 100% sold on that but you never know.

 

[Lord Khan]

Well, I got them from Extreme Motorsports, and their the ones who recommended them so hopefully they are good as advertised. So far, I'm only running 16lbs of boost max so I should be ok.

 

[Defiant]

Hell, if I was getting ten bucks and more a plug, I'd piss on them while the motor's running for you.

They should work fine. Only ones I've heard to specifically avoid in turbo DSMs were the Bosch Platinums, as some seem to have shed tip porcelain when they first came out.

Oh, and SplitFires, but that was because they were just ripoff SHIT.

The only drawback to the Iridiums that's surfaced so far is the cost.

And still, the most recommended DSM plug remains the NGK BPR6ES

When I bought my car, I pulled these BPR6EKN out.
I can think of a couple ways to gap them, but I'm sure someone will tell me that they either can't be gapped, or are already gapped from NGK.

How do those run?
Do you use them?
