We haven't had a problem with the BKR7E's here. Although I take mine out everynight and put them in liquid nitrogen. Colder the better.
You take your plugs out EVERY day? That's a whole lot of work. :eek:
 
I have problems with the BKR7E's too. Well I think. My idle was ok until I installed these plugs. My idle is rough. It was so rough one time, the car cut off. I also had a CEL. It was reading random multiple misfires. The wires are good. So I took the plugs out and regapped them. Got rid of the CEL but the idle is still rough. Think I might go with the BKR6E's. Should I?????

You still have no evidence that the plugs are bad for the car. Look at the amount of people who run the car with no problems.
Look at the number of people who have posted in this thread saying they had rough idle...sounds like evidence to me. (screwy)

BTW, number is used for things that can be counted & amount is used for things that can't be. Sorry, I used to be an English major.

You're missing the point here. It's not only that the plugs are too cold for you, the letters B,K, and E are not correct. Ours needs Z,F, and F in place of B, K, and E. ZFR6F or ZFR7F is what our car needs.

True many people said they have a rough idle but look at how many people said they don't. Not to mention the opinions of 30 ppl here can't be a useful sampling. Not to mention no rough idling on my end, it could just be the production variances from car to car whereas some cars accept certain mods and others don't. Just like some people don't stall with the greddy type s and others don't.

Thanks for the english tip, its a second language for me.

minus the group of people who have problems with them

I guess myself, 505, and the others who have had issues with them are ******* retards who cant use a spark plug gapping tool, and the bkr7e should work 110% fine in our car.

I retract my statement, the bkr7e is gods gift to the MSP.

I've enrolled all of us who have had issues with bkr7es in a 6 week course on how to properly gap spark plugs as the BKR7E's are 110% problem free with the MSP.

i've been running BKR7E's for 4 months in my first MSP, and now 7 months in my second.
no ideling issues.
although i do have a stumble arround 4k, i still think it's the ECU rather than the plugs.
i will get ZFR7F's to see if it will help the situation.

At the very least, it seems like the proper spark plug numbers should be put on the mod list, as a remedy to problems that the B's could possibly cause (and have on several cars).

Seriously? I'd have never guessed it. Props man, I've tried learning a second language, but could never hope to be fluent.
 
I had serious issues with the BKR7E's. Lots of stumbling not related with the rich nature of the MSP. I switched to the Denso KJ22CR-L8's which are already gapped to .8mm (approx. .032 in.). Man what a difference they made. Just my $0.02 to the debate.

Ok. I get it. Sorry to be so slow(spin) . I can get these at Auto Zone right??
 
So does anybody know of a website to get these plugs ZFR6F. Just searched and didnt really find anything right away.
 
Yea I guess I must be the best gapper in the world, along with the other people who have no issues. You just don't get it do you? Some people have got the car the run well with standard reach, some haven't. Some people have got the car to run well with extended reach, and others haven't. Ever hear of production variances, the same reason some people run 5 psi stock and others run 7. Or why some ECUs run far richer than others. Just because it didn't work for you or you had issues doesn't mean the rest of us have.

I have repeatedly challenged you to check my car out, or some of the other cars out in the area that have the same plugs and the best you could come up with is some lame sarcasm. So by your reasoning I guess the rest of us that have no problems with the spark plug are some sort of automotive gods that could make a spark plug work in any situation.

But you know what, you seem to know everything. I'm glad your car is running better, enjoy the car and the forum.

Agreed, I'm not opposed to people using it or it being listed at all. It could be just the ticket for some people. My entire thing was if it doesn't work for some doesn't mean it won't work for all.

by the way thanks, although I started learning english at a young age. Just as a child I used to mix the 2 languages constantly as my parents would speak to me in both.

It the B's work fine for some, and don't work for others. It's just another testament to the severe lack of consistency between MSP's.

I'm changing the recommended plugs in the modders' guide, because I believe you have a better 'chance' of the newly recommended plugs, because they are closer in design to the stock plugs.

But like everything in the guide, it is only that - a guide. It is up to each owner to decide what is best for their cars. The guide is only there to push them in the right direction.
 
Wow, stayed off a few days and this thing is 3 pages longer...to whoever it was who decided to "own" me. If you read my thread you'll notice I had a little quip at the end that said basically I was not attempting to run my mouth or talk s***. I was staing the obvious, I also never made reference to a specific plug, I just said that Iwas tired of people bitching in general when they take advice from the guide and then complain b/c it didnt work from them. Now regarding age, I hold 2 degree from the Georgia Tech....that would be mechanical engineering and astronimical physics(both obtained in 2001) Im now working on a 3rd degree in International business...oh did I mention I speak 3 languages...Now automotive background I'm ASE certified, I've built upwards of 40 performance engines and cars, I've custom made more parts than you have on your car, and I could go on and on but I think I've made my point...I hate people who sit here and talk like they know cars just because they can install a mbc, and change their oil so dont think for one second you can school me in anything about cars, math, or anything requiring intelligence for that matter. Just b/c I'm new to this board doesn't mean Im new to the performance world... and yes this is talking s***...I was nice enough before, but if you dont show me the same courtesy I wont return it...oh if you'd like to check my credentials I'm here in Lutz, FL and would be more than happy to back up what I said...
