OEM Plugs from the stealership!! i replaced my stock plugs a couple weeks ago with some aftermarket ones, but they started giving me problems with misfiring. i replaced them last night with plugs from the stealership and my car runs like new again.

I've been running Denso Iridium IK22's for a few years. They work good for me.

Thanks again to Dan, in case he crosses path with this post.

Where did you pick up those IK22's. The cheapest I have found them for far is 54.88 for a set plus shipping. Any place local they can be picked up? Thanks in advance.

I use NGK BKR7E's. Here's an interesting article on why you should run regular copper plugs in a high boost application:

YMMV.

Autolite Coppers work great and are dirt cheap.
You can afford to put in a fresh set every oil change.

wow, this thread might have just answered why my check engine lights been going on. the code reads Air/Fuel metering. i thought it was a problem with the sensor, reading a thin mix due to the air intake. Maybe its my spark plugs hmmm......

[1965truckrod]

I am going to pick up a set of those NGK's from that audiworld post tomorrow and see if what they said is true

I threw a CEL just by putting Bosch Platinum 4s into my car (due to mention massive misfiring caused by the plugs); swapping them back (and replacing the plug wires someone damaged in the process) fixed the problem.

Only time I've ever seen a CEL on my dub in nearly three years ... so plugs can definately do it. Never got a code read though.

well I was going to try those copper core plugs to see how they work but they are special order everywhere I went but I only went to pepboys, kragen and autozone. I am some what limited on how far I can stray from my house and work during the week and I would like to get this changed as it is coming up on my oil change and I would like to knock out the plug swap while I am at it. I am going to try veeparts and see if they have them. They are just down Magnolia. Thanks for the help though.

[bronfufu]

if you guys want NGK BKR7E buy itfrom JOE SAMPANG @ 2ndIInone!
JS2ndIINone@aol.com

here is his email, this guy shipped them to my house for like 12-13 bucks! ... and man he even wanted to meet halfway just so i can get them in time.. all for just 4 plugs, that great service.. ! just passin the word around to the community

Go hit the motorcycle shops. I get my NGK plugs at a local dirt bike place.

[1965truckrod]

I got tired of running around to find the BKR6E's so I just ordered them directly from NGK also that gave me a chance to order a set of 8 or the 6's and also the 7's so I will have them available when I start doing my upgrades or if it gets a bit hot this year and in addition to some upgrades I can compensate. I use to have to change plug temperatures on my 65 Chevy all the time so I am buying the colder plugs just as a precaution also. They are being next dayed so hopefully I can change them and my oil and filter and do a few other things while I am at it. Thanks for all the help peoples.

I am a true believer. The engine doesn't seem like its struggling, it has a deeper tone even through the stock exhaust, it develops more boost and the boost stays longer. I will buy these plugs from now on.

[jr_scheiBe]

I got a box of them for $12 at Napa up in Kearny Mesa

[1965truckrod]

I never tried Napa, its ok though because I have enough for a while. I will keep that in mind though. Its the copper core BKR6E's right?

Tell me how the plugs change the exhaust tone, develop more boost and hold boost longer. I just don't see how they can do all that.

[1965truckrod]

Well they burn more efficiently, I remember when I use to pit crew at Cajon Speedway I remember we use to use just regular plugs because they have a perfect burn pattern but don't last as long, since we would replace them all the time it didn't matter. As far as the exhaust tone, when the engine is burning all of the fuel in the combustion chamber completely and running much cleaner it will have a deeper sound since there is more of an explosion then with the platnium plugs that are meant more for longevity and don't but the fuel as well. Being that the combustion is more efficient and complete you will have more of an exhaust release and produce a higher velocity of gases coming out of the exhaust ports thusly producing more boost when it spools the turbo, Since the turbo is getting more boost is won't have a tendency to drop off at higher RPM's because it is one again buring all of the fuel. Since there is more boost the fuel mixture will have to change to make up for it and that brings the whole system up a bit. I am just going off of theory now whether the engine is actually doing that I am not sure but you can feel the "Seat of the pants" difference during dead stops and high rpm shift runs. I should have thought about it before with the regular copper core plugs but I didn't realize how much of a difference they are compared to a platnium plug that comes in the car. The stock plugs are NGK Platnium plugs with the AUDi/VW symbol on them. You just have to change them alot sooner then you would a normal oem plug. I haven't a problem since they are so cheap, thats also why I purchased a couple sets of the plugs. I also got the R7's too because I eventually plan on getting the chip and I would like to experiment with colder plugs.

so does that plug differance also go for the supercharged cars like corrado and what not?

[1965truckrod]

It will if you are running Platnium plugs or anything that isn't a solid electrode and regular plug, Platniums and irridium are very hard and are designed for longevity not performance persay, they get much hotter and can cause pre ignition which you don't want and in a supercharged/turbocharged system you get hotter combustion from the boost. Copper core is the way to go in performance and Efficiency of fuel burn but you lose the amount of time between plug changes, they are super cheap so it really doesn't matter.
