Yes. Both are listed on the owners manual.I would go OEM. Only engine issue I ever had with my 4Runner was due to aftermarket spark plugs.
My bad.Yes. Both are listed on the owners manual.
I should have been more clear with my post/question.My bad.
Whatever you do be sure that you purchase from a verified vendor. Lots and lots of Legit looking, but ultimately FAKE plugs out there especially on Ebay and Amazon.
Interesting fact, on some Toyota motors, My 2007 FJ for instance, come from the factory with both. One side has Denso and the other NGK. Now I do not know about Cruisers since I picked up my 2006 LX470 used. Why did they do this?
That’s interesting. My dad said the same thing about his 2005 Tacoma years ago.
I do like TTs, for two reasons.This is 100% accurate.
2001LC is using some twin tip Densos right now. He seems to like them. For most people who just want to set it and forget it stock feels like the best option. You know what you are going to get. Scored 2007 LC W/63K No AHC Clean. Adding Lift, Sliders & skids!
I do like TTs, for two reasons.
1) China has not been able to boot leg, the very thin .04mm tips of Denso TT. So I can spot bootlegs easily.
2) Denso claims lower power draw with TT, for same or great spark. This lowers coil temp, or is to say, coil runs cooler. High temps damage coils, so cool adds to life and they age with a more even power curve out put. It is why we do not want wide gap in plugs, beyond spec. Wide gaps draw more current to get spark. BTW TT are gap at 1.0mm vs book of 1.1mm new. It's also why as spark plugs walk out we blow coils, as they draw more and more power trying to achieve good combustion spark.
We have issue with spark plugs walking out. I've been hear and seeing "some " anecdotal evidence this is a Denso issues more so than NGK.
Ticking time bomb TICK TICK TICK: Spark plugs Alert Alert Alert!
TICK TICK TICK POP POP POP is a ticking time bomb, often mistaken as exhaust manifold crack or gasket leak leak. ALERT, ALERT, ALERT: Spark plugs are working themselves loose. "Walking Out" Then blowing out of head, taking their female threads of head with them! Very damaging! You think TICK...forum.ih8mud.com.Genuine or Bootleg parts
I buy a lot of parts from on-line sellers these days, mostly form parts houses or Dealerships. Now and then I'll but from say ebay or Amazon. Seems I get Bootleg from China more often from ebay sellers. I've had some of those low priced Denso coils that look so good. But with close inspection...forum.ih8mud.com
Note: never re-gap used plugs.
No, it was common practice. One bank got Denso, and the other NGK. Weird stuff. This was a standard, not random. When I worked for Toyota parts back in the late 90's, techs said the same thing. They always knew if the plugs were original because of this. Toyota did this for years, if not decades. My memory may be a bit clouded now, but I swear the techs noticed it during the massive V06 campaign with the 4Runners and Pickups. Why did Toyota do this? I do not know, but I would love to know.Could be the assembly plant, the techs was using whatever was on his tray?
