I used Bosch platinum plugs in my old (1989) Peugeot 405. The mechanic at the dealership was horrified and always changed them back to the factory brand (which I think were called Eyquem) and it was easy to tell because the idle was rougher. The only difference I could honestly tell the Bosch made was the smoother idle, but there were certainly no problems.
The Peugeot had an aluminum head and I liked the smoothness of the threads on the Bosch plugs. They weren't as sharp as the threads on American brands like Champion or Autolite. Seemed to be a lesser chance of cross-threading. | ||

I use the Bosch in my Jeep...but then again, those are factory installed as well....
mine take 16 plugs...... Yttrium on the intake Irridium for the exhaust they are specific of which one goes where....... I too have to the coil on top of the spark plug.....and had those rubber sleeves break off down inside, as they stuck onto the plug..... had to use a screwdriver and slide it down the hole, and snap off the top of the plug, then you can remove the rest of the plug.... they hold up and work very well...... | ||

also use only NGK
in mowers, boat, old and new cars... they are the only plug that seems to hold up well in 2 strokes which fire twice as often. We used NGK exclusively at the boat dealer when working as an outboard mechanic in the summer, in 2 and 4 stroke outboards and in automotive-block I/Os and inboards, never had a failure. Can't say that about other brands.

I generally make a point of using whatever they used as the OEM plug. Years ago when the Bosch Platinum's came out I was changing them in everything. At times I felt they made a difference, although not always for the good. One car didn't seem to pull as well under load with the Platinum plugs as with the OEM standard ones.
From a machining standpoint, I always thought the Bosch plugs had the nicest threads. They were rolled well and nicely deburred. No matter what be sure the threads are properly greased before installing. Second guessing the engineers really isn't always to our best advantage | ||

Phil is right though.....when the Platinum's came out.....I installed them in my Chrysler 2.2 Turbo XT....it would start, but no power to move the vehicle....finally had to switch back to Champion's, then it ran as normal....
Champions seemed to burn out fast in Chryslers 2.2/2.5...Turbo and Non-Turbo versions...about every 30,000 mi. Chrysler had a good set-up with those transverse engines in the 80's, everything up front, even the intake was easy to remove and lift off from the back part of the engine... todays cars, even a 4 banger is packed in there tight.... | ||

I had my mom order the OEM plugs for her Sonata with the turbo after doing research and finding they don't do so well with other after market spark plugs. That car also calls for a spark plug change at 45,000 miles. Direct Injection is apparently harder on spark plugs, which that car has. | ||

My Nissan doesn't call for a spark plug change til 110 or 120k miles. I'll likely never have to change them! | ||

Replaced the plugs for my moms car today at 53k. Replaced NGK with NGK. Old ones had blow by around the ceramic, didn't look too bad but were definitely ready for replacement. Didn't notice any apparent changes in the way it ran but I took it for a quick spin and it seemed unusually powerful compared to normal. | ||

ND (Nippon Denso) spark plugs are often over looked. I think they are now marketed simply as Denso spark plugs.
