Re: Best Spark Plugs for 408W with Victor JR Heads
Thanks Joe, I'll have to try some of those. NGK's have worked well on alot of cars I have heard. I know I had a 93 Mazda MX-3 (V-6) that needed the spark plugs replaced. Ended up buying some Autolite's for it doing my own tuneup. Car seemed to have a hesitation after I installed them. Figured I had brand new plugs and that could not be the problem with the hestitation.....and thought it was something else. But after 2 trips to the dealer to fix the hesitation problem, they finally replaced the plugs with NGK's. Car ran great after that. Thought it was just the quality of the NGK's versus the Autolites. Anyone know the part # of the equivalent NGK's to replace the Autolite 3924's?? Thanks.
