Do any of those "speacialty" spark plugs (like "Split-Fire") give any significant improvement? Seems to me that a spark is a spark...  |

Spark plugs have "temperature" ratings on them. Sometimes they can ill-effect the reliability of an engine. So I've read. I figure, though, if they list a part number for your engine, you're probably in the clear.
I run normal Denso plugs. They've been working great for me.

I know 2 people that have tried them ( Split-fire plugs ) and both indicated they didn't notice any difference. This is second hand information and I have no actual experience with them. One thing that has worked over the years is if your engine is using oil and fouling the plugs, switching to a higher heat range plug can help prevent this. One note of caution is that buy using a higher heat range plug you can cause engine damage because of pre-ignition.

I should have mentioned that back in 1992 or so, I purchased them for my 1989 Honda Prelude.
NO difference, except for the $5 each they cost me!
I was just wondering if there was a difference that I couldn't see or wasn't seeing...

watch-out for bosch platinum series. Mostly the 4-tip kind...the can detonate and cause engine damage. I've used NGK V-series plugs, they are made for the japanese-motors, and have been great so far.

I pulled a set of boch + 4s out the other day and its kinda freaky what i saw. there was hardly any thing left of them. I the Trooper doesnt like the bosh 4s stay away from them. I'll post pictures later of the plugs. I put NGK G-somethings in and an very happy with them.

Bought a set of expensive NGK platinum plugs and installed. Soon after, check engine light came on. It took the mech. and dealership serveral hours of diag. to find out why misfire. He did not think of checking plugs because the engine only had 20,000 miles. I bought a set of champion's from the dealership and drove the car for 20 miles and it reset the computer / check engine light. The car ran fine, but it did not like the NGK's. They are good enough for my 700rwhp beast but now good enough to get by in my Trooper...?

I have ran the NGKs before in the trooper and they have worked great. I have around 300 miles on the new plugs and still smooth and strong. I have no question about the NGKs performance for a long period of time. I would have gottin the denso plugs if i could get them where i live but my local parts store does not carry them. Just my two cents.

I replaced 5 of my 6 with Bosch Platinums, and I immediately got a check-engine light for mifire. Had them replaced with six factory plugs, and everything is fine. Apparently, it has been reported on other sites that Troops don't like non-factory plugs. While I may have only replaced 5 (I couldn't get the darned socket wrench into the sixth hole!  ), I don't see why that should have been a problem. Oh, well. Lesson learned. |

I used Delco and Motorcraft plugs in my Trooper with no problems. It came with Champions.
