I think this is probably the right place to post this so I'll post again.
I'm looking to replace my OEM spark plug wires. I'm not concerned about getting OEM because I'm supercharged and interested in performance. I've looked on the web to no avail about the difference or compatibility of the NGK TE66 to NGK 4412 wires, especially for my specific application. I've read of gen 3ers using both, but nowhere can I find information about the difference between the two. Any input would be groovy.
Also, I just ordered some new plugs, after getting the NGK plug code manual, and the printout of the entire part number to stock number of the NGK catalog, here:
NGK Spark Plug Codes
http://www.ngksparkplugs.com/pdf/StocktoPart11x17.pdf
I haven't seen the topic of the difference between the plug wires anywhere so fire away.

4412 is the stock number, TE66 is the part number--exact same wires--no difference at all. The 4412 is like the 4-digit stock number for spark plugs and the TE66 is like the alphanumeric part number (BKR5EKB-11, for example that has a stock number of 3967). To confuse it even more, NAPA carries the same wire as NGW 4412
S/C issues I leave to others.

I'm not sure where this leaves me. I replaced the plugs with the single tip BKR5EIX-11 Radium . That was 11 months ago and have not had a bit of trouble. No check engine lights ,good performance, good gas mileage. Is there really an issue.
It seems like the OEM plugs that I took out where single tip plugs from 1998.

Yes, well I have a 5vfzfe motor, 3rd generation, and so research about the ignition system. I forget what it's called, but the plugs fire twice each rotation offthe piston, once on combustion cycle, and once in exhaust cycle. this means that the plugs need to be at least double grounded. Do some reading on it

Hi guys,
One of the NGK spark plug wires I got from sparkplugs.com (SKU: TX99A
ITEM : NGK9799) has developed a crack after just under 2 years. I expect wires to last longer than that.
Do you think it's indicative of NGK quality and I should get a Denso instead?
Or could it be just a fluke so should I stick to NGK? (Sparkplugs.com will give me some discount for repeat order).
Does anyone have any experience that sets NGK and Denso apart?
Denso DENSO Part # 6714003 is actually less expensive than NGK9799 from Rock Auto.

Update on the Denso TT spark plugs
Today at 177,500 miles (16,000 miles since the install) and I have decided to remove the Denso TT plugs. Upon inspection, the plugs in cyl 2, 4, 6, all looked fine and held their gap of .044. The plugs on the passenger side did not; 1, 3, 5 all had opened the gap to .049. Closer inspection shows no signs of wear. My best guess, the heat has softened the ground and allowed the gap to open up.
Lesson learned. I will go back to the Denso double platinum, double ground spark plugs.
What concerned me was to loss in MPG from 22 to 14 recently.
FWIW I wanted to let everyone know if these plugs were a good choice for our trucks. No.

At least you were honest with your findings.

Wires every year is overkill. I ran my factory Sumitomo's 80k and have 80k on my NGK's. Never had a misfire. I get my OEM NGK plugs from NAPA and change every 30k (NAPA is 15 miles closer than stealer.)

I service a Hyundai, a BMW, the Toyota, and a Farmall tractor, and all get their filters, plugs, wires, etc. at NAPA. It just makes my life so much easier, and in most cases it's cheaper.
There's always more than one way to skin a cat.
