Hey guys,

This one is probably gonna be a really quick answer, but I figured I would ask anyway. When I bought my $100 83 GSL parts car I found quite a few nice things that I can use, but one of the better finds was a set of brand new NGK BR8ET plugs in the engine. The engine was blown, and the previous owner said that someone had put the wrong plugs in it. After looking through all of the papers in the glove box I found some numbers referring to the Autolite plugs. Guess what?? THE AUTOLITES BLEW THE ENGINE! Another victim of a crappy product with crappy tolerances. Anyway, my good 85 GS restoration project has a set of autolite plugs in it that luckily I haven't used too much. I'm going to take them out pronto, and put in the new NGKs that came with the parts car.

Question is, what application are the NGK BR8ET plugs for? I looked in my Racing Beat catalog and it reccomends a BR8EQ but didn't mention anything about these BR8ETs. I did a little searching but all I really came up with was some vague information about hot and cold plugs. I know these NGKs will be much safer than the crap autolites that are in my good engine right now, but I want to make sure they are ok to use. Does anyone else use NGK BR8ET plugs? Just want to make sure I'm not gonna pull and Autolite and chip off the apex seals. Thanks in advance guys!

 

the 1980 rx7 used em, from what this web page has..

Hmm.. Does that mean they are a bad idea to use in an 85 12A engine? I don't know much about spark plugs, but I do know what happens when you put the wrong size in. El Blowo De Enginero....

 

Nah, it wont hurt it. The housings are all the same, plug depth wise AFAIK.

 

I used BR8ET's in my '83 engine. The only trick is you need a thinwall spark plug socket.

Then I got tired of buying $16 worth of plugs every month, and dealing with the thinwall socket, so I started using Autolite 3923's instead. THEY NEED TO BE CONVERTED TO SIDE GAP. But they work *great*, and they last a lot longer, and they're only 99c each.

 

uhh, i'm scared now. i have used autolites for a while and i just pull them from the box and slap them in. oops, should i not do that????

 

NGKs are usually recommended, but one of the guys on the REPU club swears by Autolite 2626s. So I got a set ($1.29 ea), but haven't tried them yet.

Im currently using autolite 4294...no problem except for the price. it seems it runs better but I continued to switched back and forth between NGK B9EV or B10EV and Autolite 4294.

 

i had B10ev and they suckes in my car i used before the b9ev and they worked well in my car but it was a pain to find it because the auto part place here were too dam lazy to check the dam book for part #. now i have ngks that the 2nd gen use and they work ok but i have some issues with them. i wouldnt change my NGK's for nothing

 

The BR8ET plugs have only three side wires IIRC.
They were used on the pre-RX7 rotaries.

I had very good results with B8EV plugs, but they didn't last.

 

I havent ever used the BUR8-EQ14.
allways the B8ES ,and i`ll be starting to use the B10ES the next time i change it.

I have had good service ,and they are cheap!

BR8ET's were on '80 RX-7s. I think the '79 used BR7ET's, after Mazda switched from Nippondenso to NGK.

For what it's worth, the T means 3 electrode. The Q means four electrodes. I like the 3 electrode better than the 4 because there's more "air space" around the electrodes for the flame kernel to develop.

Then again I'm recommending singe leectrode plugs (the cut down Autolites) and they seem to last longer than the BR8ET's even though they have a third as much spark area to choose from. Hmm.

 

After the recent thread about the autolites killing that engine.... I'm not gonna use anything but NGK multi-ground plugs. BR8EQ-14s seem to be standard fare, with the BR9EQ-14s being better for highway (I believe)

They're a tad more expensive, but they're mazda recommended, and many people on the forum swear by them.

I figure it's a summer-driven car that will get new plugs once a year anyway... what's $40 a year? **** man, $3.34 per month Canadian, it's worth it for my car.

Geez.. the autolite 2626 plugs don't look like "Standard" plugs at all....

I wish I knew what type of autolites blew that guy's engine..

Though they don't look multi-ground.. they don't look single-ground either.

PS: Follow-up from sparkplugs.com found me these:

They're recommended ub3r-high quality plugs for second gens... Would second-gen 13b plugs fit a 12a? I can't see the length being any longer... but I'd hate to pay $35 per plug just to screw over my perfectly good engine!

 

The installation manual for the BAE turbo kit recommends NGK BR8ET's be used' 3 electrode the R stands for resistor without it you hear the RPM'S through the radio
