I want to do a total tune up on my gsl-se and was wondering what brand of plugs (I think NGK is a no brainer), plug wires, dist. cap, rotor etc...what else do you have to do? I am replacing the fuel filter too. The car runs ok but I have no clue as to when a tune up was done or if it was ever done?? I assume it has but....you never know I guess. It has 82,000 miles. I know for sure the clutch has never been done and it seems fine??!!!..I guess I will leave well enough alone. Should I do the same with the tune up?? Leave it alone? Like I saidm runs good, lacks the power "I" think it should have. Maybe all I need is to have the timing checked??..I appreciate your comments/suggestions...cjf

 

Spark Plugs

 

yeah, I saw that, that was why I said "ngk a no brainer"...thanks though....cjf

 

That's not the only reason why I pointed that out. There are also some interesting combo's of NGK plugs that you can use - such as BR8EQ's on the leading and BR9EQ's on the trailing.

 

I've used NGK wires as well, mostly 'cause they look good (blue) and seems like there's always a new set on ebay for around $15.
Supposedly it's best to use the mazda cap & rotor, as they will last longer.

 

sorry 'bout that, Iwill look at that closer. Did you do it and if so, any difference??

 

No problem cjf.

The next time I switch my spark plugs, I plan on running this configuration. I'll be due to change my spark plugs soon enough.

 

what's the benefit of the br9eq's on the trailing?

 

 

I'm using a set of Accel 300+ "Thunder sport" wires and am very pleased with their performance. They have a spiral-wound metal core that doesn't wear out like normal carbon string wires, and the spiral winding gives them a resistance of 150 Ohms/ft. for radio noise suppression. Plus, their red jacket looks cool.
I have a couple of sets of the blue NGK wires, but the Accels are noticeably better, IMO. I'd like to find a source for some Mazda rotor and cap sets that don't cost an arm and a leg, myself. I've used a lot of different spark plugs in different rotary cars, and have settled on the NGK BR8EQ14 as the best balance between power and longevity. The best power was achieved with NGK B8EV plugs, with the most difference being felt in the midrange. They didn't last long enough for me, though.

 

how does a set Accel 300+ plug wires give you performance over normal plug wires..how are they "noticeably" better??.. in what regard...thanks..cjf

 

The car just seems to have a smoother midrange with the Accels vs. the NGK wires, 'course that's a seat-of-the-pants observation. They do have a lower resistance per foot than non-metal core wires, and they don't wear out like old style carbon-string wires do. So theoretically, their performance should not degrade with time. I got them at the junkyard for FIVE BUCKS, how could I go wrong?
