I recently learned the hard way as did another friend, on the same exact day. Dont use either Denso iridum nor Zex turbo/nitrous plugs (they are actually made by champion)

please heed my advice if you love your engine.

 

Thanx for the heads up Geoff!!!!!

 

Details??? What happened?

 

what happened man?

 

Geoff, I already knew this because viren told me the same thing a while back. I didnt believe him untill he showed me some results.

C'mon guys give us some information on what youre talking about. I ordered some of these plugs and want to know what the deal is cause if i shouldnt use em I wanna know why.

 

What's the deal with Denso iridium's?

 

Beleive me when i say do not use the irdium denso or ZEX turbo/nitrous plugs in your rides. They are scrap compared to std NGK plugs.

I have tested alot of things during my racing seasons and i can verify that they indeed will blow up **** inside your motor at high rpms. I have seen it done in person. They jsut start to fail at high EGT and high rpms loads.

 

Ok well which NGKs do I need to get for my 2000 Integra LS thats going to be equipped with 55 shot zex nitrous and what do I need to gap them at?

 

bcpr6es11 or bcpr7es11 gapped at .036

 

i think most people use the 7s, is that what I should go with?

 

usually for every 50 shot i would go 1 step colder from the factory. the 7s would be fine i would also reccommend retard timing by couple of degress

 

NGK's ehhh
gotta go with BOSCH dual prongs

 

The 6 means one step colder, 7 is two steps colder! Go with the 7's if you run +50HP over stock or more.

 

What about the NGK Iridiums? If they suck also does NGK at least make a plug that is 3 or 4 steps colder. My last run of the season i cranked the boost up a little bit higher than normal and the plug (Autolite 3942 gapped at .32) evaporated. No detonation or high egt's the whole tip it just disappeared. Any suggestions on what plug for my new motor 2.0 LS with plans to boost 24-26 psi.

 

I should have taken a pitcure of what my Denso Iridiums looked like after just a couple of months. The electrodes were completely rounded off. They looked like hell, and performed worse. I learned my lesson. Thankfully it only cost me a set of plugs. I stick to NGK now.

 

i use this specail race plug from NGK its number 11 plug 6 steps colder
650hp with no prob r5671a is the part number its a race plug you need it 14mm

 

I hate changing those things out after every run..

 

BCPR7E-11's here.. work great except I have a little trouble starting more often now and the occasion stumble while driving at low rpms. From what I gather it's simply a cold plug issue, but for 10psi, works wonders
