WR7CC+ verses W7CCO

[Wildthings]

Anyone have experience with both these plugs? Always got incredible life out of the stock W7CCO's and very short life out of the W7CC's. Was wondering how the WR7CC+'s did.

Do a search, many reputable sources are using NGK BP6ET and love em.

WRCC is a resistor plug. The way I see it, if the spec plug is a non-resistor, then there is noise suppression resistance in the spec'd wires, so adding resitance is going to reduce spark energy. Just speculating, but you might not like the WR's as much. I suspect there might be a palpable decrease in peak hp, and idle and off-idle response may be suffer. Try 'em and see! What's $20 these days?

Now for the shameless plug (get it? Plug?): you will like the BP6ET's so much you will never go back. How many times on this forum have you seen me advocate a particular approach with anything approaching passion? Not often, I'll warrant; I like to let people make up their own minds. In this case I make an exception.

If you just like Bosch, because it's OEM (some people do have that little hang-up, never understood why), Bosch makes a tri-electrode that I've used and it also performs better than the singles. The NGK BP6ET and the Bosch tri's are both copper core, which seems to have the best conductive characteristics for the stock ignition.

I am running BP6ET's, so I know how they run. They are fine for now, but I doubt that they will run the 80,000 miles that the original equipment Bosch W7CCO's did with ease. My 83 1/2 is pretty ratty and builds up deposits at a faster rate than it should, I haven't run the BP6ET's long enough to know how they will do, but the BP6ES's I tried gave very poor service, they wouldn't out perform a set of very high mileage W7CCO's.

Don't know what the "+" at the end of the Bosch plug number means.

So, a couple of you are running the BP6ET by NGK. I was on their web site the other day and they recommend a BR6ES for my 1.9L Vanagon. The differences are the BP is a projected insulator vs. the BR which is a resister type. That's been discussed in this thread but the T vs. S at the end is T = 3 ground electrode and S = standard electrode. Whats the advantage to a 3 ground electrode?

BTW, I've been running the W7CC Bosch in mine and recently went to a BP6ES based on a recommendation from a friend. In just a couple of days driving back and forth to work I haven't noticed a difference.

One reason for the resistance is radio suppression. Another reason is for extended tip life. That's pretty much the extent of it.
The " + " means plus. Bosch Super Plus. Plus a freakin' resistor

NGK BP6ET plugs have changed my life!

Well, not really, but I can definitely recommend them!

At Tencentlife and other's recommendation, I recently changed over to these plugs from the stock Bosch W7CC's on my 2.3L wbx. Driveability, especially in mid-range power and throttle response are noticeably improved. I have also noted an ever-so-slight increase in gas mileage, but I will be monitoring this for several more tankfuls to verify.

Granted, my engine only has about 11K miles on it, and it ran pretty well with the stock plugs. However, the NGKs have made a noticeable difference.
