Are these plugs any good on a SS/SC? Got the usual random misfire code, and high RPM stumbling. I was thinking about switching these out with the BKR7E ones.

Thanks.

 

My god, you're running non resistor racing plugs? That is a horrible choice.

It cause RFI and will mess with your ignition control module. It even warns about this on NGKs website.

 

Tag stage 1. These came with the package. I gapped them at .035.

Um ok, nice edit. Like I said, these came with the Tag kit, and I have been suspicious of them from the start.

 

Nevermind, I'm sorry. That shouldn't be used on our application. Almost any other plug would probably be better. Check this out:

From NGKs website about resistor plugs:

At the moment the spark jumps the gap it causes a high frequency burst of energy, this is known as RFI','1','1')">RFI (radio frequency interference). This is why resistor spark plugs were introduces in the mid 1960's. Placing a resistor within the spark plug suppresses the RFI','1','1')">RFI. Without resistor plugs in your car you can experience static on your radio as well as interfere with other sensitive electronic equipment. Some later model vehicles as well as newer Powersport engines must use resistor plugs for a proper "talkback" to the electronic ignition. Outboard marine Capacitive Discharge Ignition (CDI) such as used on some Johnson and Evinrude marine engines require a special inductive type resistor ( as used in NGK Z-type spark plugs). Use of non-inductive resistor type plugs on these motors can cause misfire and poor performance. For automotive CDI high output ignition systems systems (such as Mallory, MSD, Crane and Accel), refer to Resistor plugs for race engines in our racing and tuners gallery for information relative to modified motors.

 

Thanks for the info. I am really not sure why these were included in this stage kit. I didn't know about them until doing some research last night. This is in no way a "race" engine!

 

Yeah....At first I thought you had went and bought them haha. Anyways, search "Spark Plugs" and you'll get a good idea of what people use for what around here.

Edit: On Tag's website they say they include the 7Es which is the proper plug to use. They must have sent you the wrong plugs; that's messed up.

 

I wouldn't even have known where to find these! I pulled up all the old threads and got the correct numbers for the NGK, ZEX and even Autolite.

And yea, that is pretty messed up. I honestly was expecting the BKR7E's.

Looks like they are supposed to come with the stage 2 kit. Strange...

 

I've got those plugs, I'm running a 2.6 and 60lb injectors and the work the best IMO. I have the Autolites, and NGK BKR7E.

 

ive never had an issue with the bkr7es, hence why they are in my car as we speak.

 

Yeah, the NGK BKR7Es are good; it's the race plugs TAG sent him that aren't good for his application.

 

NGK recommends a cooler plug if you do anything to your car even add a higher flow air filter.

here are your options:
Stock oem PFR6T-10g laser platinum
iridiumIX. stock heat range is BKR6eIX
Recommended heat range for any mod or if you use ethenal blended fuel which is most of NA BKR7EIX

GPower cheaper platinum version then oem. BKR6egp Stock heat range.

NGK recommends that you stay away from any plug with a nickel core.
