I just picked up a set of the Bosch Platinum+4's for my 93 diamante.
The dealer told me that these plugs don't work well in Mitsu's does anyone have any experience with them.
Also are there any tricks to getting the plugs in the rear 3 cylinders? do I have to take off the air chamber or can I squeeze my hand and wrench in there?
Thanks for any help you can offer.
