bosch platinum 2

[93MTXSHO_STUD]

anyone used the bosch platinum 2's. I've had them in my car for some time now and am about to clean the intake manifold and was wondering if anyone had problems with them. I read other posts saying the fine wire plats from ford are the stock replacement since the double plats are discontinued. Just curious.

i take that is a no. well of course i read previous posts saying not to buy them, but no one really mentions why. i pulled one of the front plugs after about 40K and it looks fine, but i might just switch to the autolite double plats. ive never had problems with them. get almost 30mpg driving on the highway.

Yeah I Work At A Parts House And Would Not Recamend Them I Was Running Platinum 4 Plugs And About 2 Weeks Into The Use Of The Plugs It Started To Miss Fire Like Crazy The Electrode Broke Off Anf If It Wernt For The 4 Post Design Holding The Electrode In It Would Have Fell In The Cumbustion Camber Theres No Telling What Would Of Happend The But I Tell You What Bosch Would Have Benn Paying For A New Engine

The Bosch platinums are great plugs - for normal cars. The SHO is not a normal car. See, the platinums only have the anode (the tip) platinum; the electrode (the forks) are a regular material, and they wear very rapidly on the double-spark system of the SHO. They don't last very long. You have to get a double platinum plug of any sort for them to last much past 30-50K miles.

Autolite APP3924 or XP3924 (the hot shit ones) are the only "approved" spark plug for the SHO. This comes from millions of miles of testing... by us.

yea i just got some APP3924's today. I haven't had a problem with the bosch 2's,but I don't want a future problem. Now the spark gap is 0.044" is this correct?

ok so i agree with everyone when they say bosch plats are crap. Last weekend I took the plugs and replaced them with autolite double plats. My car definitely runs better. When I took the old plugs off I noticed that 1 was completely shot, 3 were ok looking and 3 out of the 6 had most of the plat electrode melted off/ dissolved.

.044 is perfect. You can gap them closer if you'd like a little hotter spark, but that will only work on cars with weak ignition systems.

I maintain that Bosch 2 plugs are great plugs. But not for the SHO. If you have an impala or whatever normal car is out there, Bosch plugs are sweet.

The double plats are only needed on bank 2. This is the negative firing side of the coils.

I have used both. Never had any problem with the Bosch plugs, but the Autolite Double platinums definitely made the car run better.

I would not put bosch plugs in my lawnmower. They tend to be garbage. I have no proof to back that up, but I dislike them greatly.

SHO's like ford or autolite plugs.
