I wonder how good plain copper core plugs will last in a turbo?
 

I replaced the high end $14 / plug Bosche plugs with some cheap-o $1.79 NGKs. I just wanted to get the car running again and will probably upgrade later ..... so far it runs great.

I use ngk in mine

+1, no troubles

I've used them for the twin plug, no problems.

Dude,

You'd better hope the PCA admissions committee doesn't catch wind of what you're up to, cheaping out on proper German equipment... ;)

Which NGK are you putting in?

DENSO U Groove
 

I had the same situation happen where I didnt have W3DPO's available and went to Auto Zone and bought Denso U-Groove W24ESR-U for ~2 bucks a piece and they have been working great. No Problems. I don't know ...15 bucks a plug is a bit much! I think a plug is a plug as long as there not out of the heat range and at least platinum. I may be wrong, but why such an exclusive plug for this application??? Ever consider grit blasting the electrodes with that Harbor Freight Plug cleaner. I bought one and did my 3DPOs and cleaned and inspected them for entrapped grit. Was going to reinstall them and my buddy said don't take the chance of grit getting in a cylinder. Throw them away. I dunno. This cleaning process has been used for a hundred years with success. AS LONG AS YOU INSPECT THEM UNDER A MAG AND MAKE SURE THEY ARE CLEAN..No grit anywhere! The 3DPO will clean up nicely and ready to go another 15K if you clean them..Just a thought..

I wonder why we are surprised when this happens.

I use NAPA (Wix) oil filters.

And Goodyear tires!!! Aahhhhhhhhhhhhhhh!!!!!!!!!!!!!!

VW does the same thing for their VR6 engine. The OEM plug was made specifically for that engine and they are $10-15 each.

equality, whats up with your avatars, ummm dick, is that a dick?

No, it's a tallywhacker.

:p

I can't remember the PN .... WP8ES or something ... I'm not sure about the first two letters.

Hmm...how hard are you on your car? I guess standard copper plugs are perfectly OK for street driving. Original specs for turbo plugs was "race-ready" super-duper cold platinum plugs that mostly got fouled on street.

I never tried this though and dunno how well it works. What heat range do you use? These engines are somewhat knock-prone so I wouldn't try hotter plugs.

NGK B8EGV always worked for me. Did they get sooty on street? Yupp. Did they ever missbehave while wringing out the cars neck? Nope. I must be getting old...being conservative and all :)

I am pretty easy on my car because;

1. My need for speed is satisfied on sportbikes.

2. I can't afford to blow the car up and have to rebuild it.

3. I don't have a 3rd reason ... sorry. Please go back to 2. :confused:


I imagine the copper plugs will be fine. I'll just run them until the cars starts running crappy and then change them out. :)

Jerry very sick man but thats what I thought Too!

Copper is a better conductor than platinum. Copper plugs work just fine, they just don't last as long as platinum plugs, so you will likely have to replace them a bit more often. However, as cheap as they are that's really not a big deal.
