I am debating on weather or not i should get a 2.9 with ngk's plugs becasue im not sure on how to install and gap the plugs. Is there a how to on the site. I couldnt find one. I dont want to damage anything so any help would be great.

 

ngk-bkr7e @ .040 will work with your mods.
buy a gap tool and a few extra (cheap) plugs and practice....

 

very easy install. first thing I changed after I got my stage 2 installed. Bought a set of 4 plugs (BKR7E) and gapper at advance auto parts for like $8.

 

if the plugs are iridium you cant use the gapper to actually gap the plug, only to measure it. us a screwdriver or something to move the metal piece up or down. its kind of a hard way to do it, but if you use the gapper tool it will break off the iridium tip. i found out the hard way.

 

Ive been reading, what if i get the zex plugs which are already gaped at .040 which is ideal for 2.9 pulley.

 

That's what i'm running right now. Runs great!!

 

sweet looks like im going to do that, how often should i replace the plugs though

 

I have these as well and they make the car run alot better IMO. I havent tired the NGK plugs yet.
I am going to check my plugs at 6 month intervals I think. Depending on how they look, I might replace them once every 6-9 months, but I'm not sure yet.

 

I've had some bogging with the NGKs.. i think I'm putting the stock plugs back in

 

What kinda boggin do you speak of ? Have crappy throttle response ?

 

you guys make it soo hard to decide!!at first i was gonnna get zex cause they are pre gapped and they got great reviews then i started reading some bad reviews for ZEX and alot of good ones fro NGK so i decided i wanted them but then peoeple are speakin bad of NGK. I CANT DECIDE.

 

Only one way to find out for yourself. Get a set and see how they work.
I've noticed with my A/C on, that my car can bog a little if I shift too low, but if I shift high enough, or dont have the A/C on, then its no problem. Zex are still working well for me.

 

i got the zex in now and i havent had any problems with them but i got a set of NGK BKR7Es on the work bench, i dont know what im going to do, also the zex plugs are gapped at .035 not .040

 

its personal preference as to brand.... they all work well but it does depend on our aftermarket upgrades and other factors. in reality you could also run autolight and champion and bosch along with the OEM which are NGK or the Zex. the plugs come pregapped but you should always check. the Bkr7E IX are iridium and seem to work well but i have also heard good things from the Zex. for some reason though i think they are rebranded Bosch. if im wrong please excuse me..

 

from what little experience I have, gapping plugs seems somewhat relative to what your specific engine likes. some gaps work for some people's setup, and then not others..

best thing to do is use someone else's as a starting point, but test drive and then gap appropriately.

 

always start with oem gap. then depending on factors like performance mods etc etc gap accordingly

 

Would it be better to run the bkr7e ix or just get the bkr7e? I am in the market also.

 

the IX's are the iridium version

 

So how much better would the iridium plugs be over the others and what are the benifits from them?

 

they arent better IMO.

from what i understand they offer similar performance to a copper plug, but last alot longer.
Someone with more knowledge than me will chip in im sure.

I like running the NGK coppers. I know they will wear out quicker....but i dont have any problem changing plugs more often if it means giving my car the best possible plug. (again thats just my opinion)

 

Were is the best place online to by them? No one around here carries them.

 

autozone carries the ngkbrk7e, I think the stock number is 6907
anyone have a box to double check..?

 

Autozone is like 2hrs away from me. I have Napa and Schuck's

 

how soon do you want them..??
I should run to the store and mail you a set
The number is actually 6097
Intense sells them for $2.49 each and $12 s/h

so, I'll send them $20

 

Thanks for the offer Doc but I talked to the owner of my local napa dealer(that we spend $10,000 a month at) and they said they will get what ever I want. She ordered them and gave them to me for free because the kid was being lazy and gave me the run a round. She said he is always that way and would fire him if he didn't work for free(son)lol.
