Yeah SS FTC from URD. Fuel map or timing map?

 

Both? Pretty please with goat droppings on top

 

Same here. I am about to drive down to OBX in a week and wanted to do a tune up for the first time since I bought it 2 months ago... I had just planned on buying whatever Autozone recommends, but now I am not so sure. What are the recommended plugs and wires to buy for a 2000 4Runner 4wd?

 

If you have a N/A engine, just get the recommended (OEM or NGK) dual ground plugs; same for the wires.

 

Thanks. I am N/A. I am about to go up to Autozone now. They have quite a few NGK options listed, would any of them be ok? I see they have the iridiums for 6.99. Are they worth the extra money?

Edited... removed the link. Realized it was tied to my autozone account, so it would not work for anyone else.

 

If it is NGK, get BKR5EKB-11. That is all you need.

 

NGK Wires Deffinitly!!

Or Oem but this is reccomended!

 

I barely come on here, but I figure I'd let you know I seem to have fixed my issues. (I was leaning towards the APPS, Accelerator Position Sensor)
I have been doing tune-ups on 5 vehicles right now, and when I got to the 4Runner... After I replaced a couple hoses, I started by doing a carbon cleaning. I SLOWLY sucked about a gallon of water total through the brake booster on two occasions.
Lo and behold, the stumbling is GONE.
I know one vacuum hose was 'fraying' but there was no vacuum leak, and even after the hoses were replaced, it would still stumble at certain RsPM. So it seems that there was a build-up of crap in there.

I used other chemicals afterwards just to make sure things are clean in there.

 

"that would be the TPS throttle position sensor" Sorry OCD

 

So your lean issues were related to clogged vacuum lines? Please elaborate.

I wonder if the slave igition wires are carbon? They don't have a maintenance interval but if they are carbon, they will break down eventually. I just replaced mine with some sort of three core (copper, carbon and sprial) along with plugs (BKR7 IX I guess I'll have to watch ground wear). Runs a bit smoother I must say.

 

It's time to change the plugs on my 3.4 so I decided to do some research on the VK22's. I emailed Opie Oils (Dale, I assume this is the European outlet you mentioned previously?) and they no longer ship to the USA due to "Delivery Problems". I called a couple other places, but no luck either.

I guess I'll go with another set of IK22's, or maybe the NGK's Eddie mentioned above and maybe they'll be available next time around.

 

I was really hoping they would start selling them here, too bad.

 

good info

 

I may have made a mistake, but today I installed NGK Iridium (BKR5EIX-11) spark plugs, plus Autolite Professional Series wires, into a '98 4Runner Limited V6. These plugs are single point instead of dual. They ran reasonably well in testing afterwards, but didn't wow me. Not that they should. But time will tell, and I'll post an update after a few weeks. I haven't spotted any threads or posts (yet) where these were used, so let me know if you've tried them.

Basically, I bought these after checking out sparkplugs.com and reading various reviews on the Advance Auto, but I wish I had checked this thread - especially the part about reversed polarity. Like others have noted, the previous driver's side OEM's were in decent shape, but the passenger side OEM's were very degraded.

Update 3/10/10: Actually, I like these NGK Iridiums more and more each day! I can floor it, and accelerate with no hesitation, no missing. They seem to be doing just fine, despite my earlier apprehension. I would buy them again, except I would try to get platinum on the ground. I'm looking forward to pulling them in about a year, just to see how they're doing. Maybe talk myself into a compression test or something...

 

I've never used them, but I think the NGK "Laser series" iridium or platinum might be good for our trucks because they have a platinum tipped ground. Like the BKR5EKPB-11 for NA. Or the cooler one (BKR6EKPB-11) for boosted.

 

So this may be a dumb question but are some of you guys saying that there are different spark plugs for each side of the engine? I am not sure after reading this if this is just for guys with superchargers or what? Is this an issue of plug lifespan or performance. I just went to Toyota to get new plugs for mine (non-supercharged) and they just gave me Denso K16TR11 in a Toyota genuine parts box. All the same nothing different for each side or anything. Tell me more.

 

There were from the factory, or most people have found that the case if they are the first to replace the OEM plugs.

Its for NA or blown, we all have the same "wasted spark" ign system. Maybe you need to re-read the thread. Its a lifespan issue. Most are replacing with all the same plugs.

 

Just an update, the BKR6EKPB-11 have work out good for me....note I have a SC
