what type of plugs did you put back in

Ford motor in a Mazda or a Mazda motor in a Ford?
My '91 Escort was all Mazda.

 

Ford 2.5l v6 in a 2005 Mazda Tribute. Basically a Ford Escape with different headlights, grill, tails, trim, badges, etc I remember this crazy 72 Ford courier my dad had got somewhere real cheap from a friend back in 76 or 77. It had a Mitsubishi 4 cyl in it and someone had put a header with a bigger exhaust pipe. It sounded like a crop duster and blew sooty condensation on the garage wall. We used to crack up laughing driving this thing around. Ford has done some "interesting" blends over the years, not that the header and exhaust were factory on that thing tho.

 

The spooky thing is that Jaguar quality actually improved when Ford took over!

 

If you've never checked them... How do you know there hasn't been an issue?

Verifying part condition prior to installation saves a LOT of time downstream. Just ask the tech who installed a brand new faulty turbo in my Jetta.

And yes, I worked as an auto mechanic for several years. Now I work with aircraft where NOT taking shortcuts is even more critical

 

Denso Iridium for my girl. #

$53 SK20HR11 ---- IRIDIUM PLATINUM power pack Spark Plugs -- # 3421 ----- 6 PCS NEW

SK20HR11, picked them up at 20% off Advance Auto had running on parts.

I will put anti-seize on them and then check them at 30k miles.

 

No reason to use Iridium in the 4.0
If you do, there's no reason to check them at 30k.
Iridium plugs will go 100k. That is the ONLY reason to use them. They don't perform better, they don't improve mileage... they simply last longer.

 

I run them in my Avalon XLS and since they last longer, even better. I almost bought double Platinum instead.

 

I bought Densos from this Ebayer.

They have the right Toyota part number on there, but the description is wrong. Anyways, I received mine quickly and they were 90919-01235.

Good price too. I was told the local dealer sells them for $3.25+tax each. Saves me gas money.

 

Well I got around to changing my plugs today (installed Denso Iridium) and I am glad that I did. On the passenger side were Denso, and on the driver side NGK. Most of the plug gaps were way off from wear but the overall color of the plugs looked good with the driver side with just a very slight oil film. I assume this is because of the PCV valve. Also the only reason I can figure the factory uses two different plugs is for the heat range, maybe a little hotter on the driver side to offset the oil vapor getting through? Does anyone know why for sure? I kept the old plugs and could check the models heat ranges to compare. And naturally everything got anti-seize, there was none on the plugs I pulled.

Oh, and after changing the plugs on my last truck, a 1998 Ford Ranger XLT (2.5 L 4 cyl) with eight spark plugs, this truck was a pleasure to do.

 

I think it's just to keep a relationship with 2 different vendors so they will always have a supplier in case there is a problem with one or the other.. I could be wrong - I was wrong once B 4 - but I doubt it.

 

That's my feeling as well.
Rather than try to run Denso in some models and NGK in another model, which are going to fluctuate with changes in sales trends, just run the "V" engines 50/50.
My '03 Tundra 4.7 was the same way.

It makes it a bit easier to provide more solid production requirements/shipping schedules to the plug suppliers, and should there be supply problems with a supplier, or if overstock results from a drop in 4-banger sales, the V6 production line can absorb some of the flux.

 

I like the way you think Rich. You and your brain.....

 

Since U agree with me I have the utmost respect for your opinion

In my '11 4.0 I used the Bosch Platinum FR 7 NPP30X at 3/each from my local auto parts store...90 minutes to change.

Bosch never more! Put them in the Contour V6, 30K later developed a miss, pulled the plugs, no easy task on two of the rear cylinders, 3 out of the six were leaking between the insulator and metal.

Gotta do plugs in my 4.0
am I going with copper anti seize or grey graphite anti seize ?
I use to use the copper for sparkies .
I am suprised that nobody is doing kilo-ohm inspections on the plug wires .
I know for a fact that Chrysler and Jeep dont last 25,000 miles
Most people are noticing better fuel economy after the plug change due to the fact that its time to change their plugs .

 

just ordered 6 Denso Iridium plugs... guy on ebay has them for 48 bucks shipped, so for 100k miles, it beats the opposition of paying 20-30 bucks every 30k miles. who knows, maybe these iridium plugs will turn my 1GR into a 2JZ with a supercharger, give me SAS, regear me to 4:56's, give me a front locker, and an ATO hybrid bumper with a Warn M12 as well....

 

We don't have plug wires.

Most Toyotas have been coil-on-plug for over 10 years.

 

Thanks Rich . I should have known this lol .
