Hi all,

First time poster....long time lurker.

Anyway, I finally jumped and ordered a s/c for my '01 V6 Tacoma.
I have all the new parts to do a 90k tune up as well, except for the spark plugs.

It was suggested that I get a 1 step colder plug to go along with the s/c. Ive been to my local autozone/checker to ask about colder plug and I get the dear-in-the-headlight-look. Does anyone have a part number for colder plug?

Also, what's the deal with dual-electrode plugs? are the really necessary on the Tacoma?

Thanks in advance

 

go to the stealer

 

I don't have any info about the cold plug part # but I can tell you that there's a lot of hype with the dual-electrode plugs but for the price, I don't think they're worth it.
You're gonna love the s/c, good luck!

 

Unfortunately, it will take more than spark plugs to make sure the supercharger will run properly with your engine. The supercharger will give you great power, but without some other upgrades you can potentially cook your engine. You should do some reading on potential problems, and their solutions. Problems usually include spark knock, lean conditions, and automatic transmission failure.

The plugs I would recommend for use on a supercharged engine are the Denso 5062 copper spark plugs. They are 2-steps cooler than stock and are pretty cheap at $20 for a 6-pack. I currently have the Denso Iridium IK-22's (also 2-steps cooler) but they have a screw-top that comes loose and plays hell with the ignition system.

Additionally, you will need a wideband oxygen sensor and gauge to tune your engine. I have this one and it works great:

Thanks for all the info Mastacox,

I was also concerned with the lean condition. I don't normally do things half ass, so I researched the URD kit. I was finally told that since I'm at 5k feet+ (Denver) that the high rpm lean condition would not be a problem. I will eventually end up doing it, just for piece of mind (and know knows, it may help performance?)

I also have a manual, so that takes care of the tranny.

Spark knock? Will the colder plugs help with that?

 

I think higher octain would help fix spark nock. Im not 100% sure though.
