Bosch plugs and leads 1.5.


New Member
I couldn't gap my platnuim plugs at 0.9mm and tried bosch mpi leads. Car didn't like either today, idle to low.

Trying to service this car seems complex lol.

Can I still get these from mitsubshi? Or are there any other places? I need correct parts .

What do you mean by you couldn’t gap them?

Why were you replacing the leads in the first place? You can test them easily with a multimeter. Any good parts shop can make you a set of leads.

Shouldnt need to down gap the plugs, factory plugs are 1.1mm, with plat plugs being no different.
