Sparking plug heat range.

Recommended Posts

post-28702-0-95683600-1364745094_thumb.jpgYesterday I installed Bosch 4303 platinum spark plugs in my ea82 by mistake when they were supposed to go in my ej22. Can I leave it that way or will it foul things up?

I wouldn't install bosch platinum plugs in anything... I used them in an ej22 once, it ran crappy, and after a couple weeks ran horrible. This is how the plugs came out.

(I'm aware the screw thingy on the top is missing, but it was there when it was in the car, that's not why it ran bad)

 

After I changed to ngk coppers, it was fine.

+1 on the anti-Bosch Platinums.

I had  three fail in less than a month after installation on a 1991 Ranger V6, that's a 50% failure rate!

Immediately yanked them out and never used Bosch Plats on anything ever again.

 

For Japanese vehicles I use NGK,

For the Scout its AC/Delco

Ranger gets Autolite

 

Has anyone here have any experience with Pulstar Pulse Plugs?

 

curiously,

timothy
