Has anyone had experience W/TorqueMaster Spark Plugs
I am looking to upgrade my spark plugs. Currently have Nippon Plugs. I am was thinking about the Bosch Platinum. Buth then I came across these TorqueMaster plugs. I anyone has any experience with them I would really appreciate some comments.
Thanks

I have used TorqueMaster plugs in my 1987 928 S4. I only put about 3K per year on the car but they have been working fine for 12 years. Smooth idle, no sign of hesitation on acceleration, etc. Can't speak to improved power or gas mileage. They have re-designed (improved) them since.
I can't think of any valid reason not to install them except cost - don't see any downside and perhaps they do, in fact, last 200K plus miles as advertised.
Does anyone else on this forum have these plugs in their Porsche?

No fancy plugs. Bosch R plugs or NGK. If you cannot find them go Champion. All the testing and real world experience shows the 'fancy plugs' are nothing more than a marketing gimmick. Spark plugs are one of the cheapest things your motor consumes, so expect to replace the once a season or so. The 928 is very easy on plugs, not like some high horsepower turbo motors that are out here. Additionally, some of the 'miracle' plugs can break, I have seen plugs with chipped insulators, broken electrodes , etc.. This ends up in your motor and you're looking at major $$.
The car came with Bosch Resistor plugs.. Go with that , NGK, or Champs. Replace once or twice a year. Easy Peasy If you live somewhere really hot or you drive extended highway high rpm miles, a colder plug in the summer months may be your friend.

At best the trick sparkplugs allow the owner to neglect changing them on a regular basis, the worst has already been discussed. Some have insulators which seal too tightly and become nearly impossible to remove the wire boot from the plug. About the only part that is an "upgrade" is the cost !!

Seargent5--
I've watched over a period of decades as various expensive "gimmick" plugs have been introduced to the market and slowly died off. One is the Torquemaster. I "tested" a set in a previous car, a Saab turbo with some enhancements. Their first promo blitz touted them as some sort of "flame injector", where the magnetic field generated by the ignition pulse would somehow cause a flame to leap from the end of the plug. Didn't happen. Then the never-foul claims, which aren't important unless your engine swallows oil, but then they fouled anyway if they did get oiled. Just about the only thing they do is last a long time in a properly tuned engine, mostly because of the way the ground electrode is configured-- you can't see the erosion. The only way to tell if tey are used up is to map firing voltage, and see when that gets higher due to electrode wear.
The current crop of gimmick plugs includes E3, and I'm not sure what they are really claiming. Most have untraceable testimonials about mileage improvements or horsepower, but the comparisons are almost always against a worn-out plug that needed to be replaced; none are new vs. new in head-to-head (sorry...) testing. Even the Bosch +4 plugs are made only so that manufacturers (MB was prime on these) can avoid replacing plugs under US emissions laws in the first 100k miles. No performance benefit, and in fact there may be some penalty as the flame is partially shrouded especially as the electrodes wear.

Most enthusiasts, including this one, look at plugs on some regular basis for early signs of engine problems. To make sure I pass emissions in Cali every couple years, a new set of plugs goes in if there are any signs of needing them. That's maybe 10-15k between inspections, new set every other inspection. No problems with that method so far, over the 15 years or so I've owned the car.
Keep in mind also that the water-cooled 928 engine is very kind to plugs, particularly compared with the air-cooled 911 brothers. Such things as Lodge plugs, silver-tipped plugs, and ultimately the platinum-tipped plugs were created for those engines that have huge swings in temperature. Those don't happen on any normal street-driven 928.
Bottom line for me is that the factory-recommended Bosch copper-cored plugs (WR7DC or +) seem to be fine in my car. My second choice might be the equivalent NGK (BPR6ES) in a pinch. So far the Bosch pieces are readily available, inexpensive, trouble-free, etc. No need to change something that works, IMO. YMMV, of course.
