Anyone using these? Any complaints/comments/suggestions? TIA.

 

I have heard bad things about those plugs, and I think they are expensive as hell too. NGK

 

They are 20 bucks on ZEX's website. How much are NGK's?

By the way, I did a search but ZEX is too short a word.

 

i would definantly skip the ZEX plugs and use the NGK copper plugs. the NGK's are normally half the cost of the ZEX and work much better.

for ZEX plugs

 

I used them on my Accord and they worked fine (nitrous app).

 

they are crap , they burn funny and uneven ,.
good ole NGKs are best.

WERD!

 

multiple electrodes-suck aaassssss

 

yea i heard they werent all that so i sold mine b4 i even put em in .

 

I didn't have any problems with my Zex plugs, but NGKs are cheaper and work. Go with NGK.

 

Me personally I didn't like them, but they work. I liked NGK's better. I don't believe in the 3 prong set up. You can only get a spark off 1. I fired my car up then pulled them back out and it fired on 1 side of the spark plug.

 

Zex plugs melted after a month on a friends car. Now using NGK's and no complaints after 8 months.

 

Hey, I'm all about Zex, but those plugs pissed me off. My motor was mis-firing with them.

I'm using Denso 2 steps colder now.

 

Thanks all, ya saved me $20. Whats the best price you've found on the NGK plugs?

 

i made 434whp with the zex plugs in my car with no problems whatsoever.if they weren't running right in someones car it was probably because of the tune.i have used them in my car,my wife's car and many customers cars and they have worked out great every time.

 

i had them zex plugs in my accord wagon with nos as soon as i installed them the car didnt run right . i put the plugs on a sparkplug machine and saw that only one side fires so i tossed them and put the ngks back in... the zexs are garbage....

 

my friend had the zex plugs in his car and one exploded inside...causeing MAJOR damage. another friend had his detonate constantly. i would stay away from them!
i use NGK one step colder....oem is always best way to go.

 

NGK iridums are some good plugs if you have some money to burn.

 

the good ol NGK BKR7E-11's are cheap and do the job well, especially with N2O.
that's what i used with my DP system last year and i had no problems with them.
they're a #7 heat range, which could even be used for turbo also, but a #8 heat range would be better for most turbo appl. only $2 each average selling cost, sometimes you can find them for less than that too.

The intent behind the mulitple grounds is to provide more sources for the spark to jump to. It's only going to jump to one ground. It's not designed to have three different sparks.

mine melted anyways so i don't use them..

 

spent 6 bucks on my ngk's at advance auto. they had to special order them, but i got them the next day.NGK
