I have a 1988 Trans Am GTA 5.7LTPI , and I'm planning my tune up parts so I'm ready to go come spring time. So this is what I am thinking. For plugs, I want to get some NGK Iridium LXs (link), black MSD Super conductor wires (link), Accel Cap and Rotor (link), and then i'm going to put Mobile 1 Full synthetic 5W-30 oil in it. I was also going to put Zmax in the fuel and oil systems. I always use premium gas in it too, so after I do this tune up, it should run super smooth. So, what do you guys think?

 

I guess i need to be a little more clear. Is getting the really expensive stuff worth it?

 

It's a matter of opinion. Mine is no, not even remotely worth it. Put your money where it will do some good like headers.

 

I agree, if the motor is pretty much stock - or even if it isn't you're not going to be gaining anything by running $6 spark plugs. Maybe .00000001 in the quarter mile via the lighter wallet. Run your standard .99 cent delcos or regular old Boschs and be off with it. If you need new plug wires, rotor, and cap, then what you are looking at will suffice.

 

do some love maintence like

flush the brake fluid

flush tranny

new gear oil

pack the front wheel bearings

she will love on ya

 

well im also going to flush coolant, and change the tranny oil. maybe the diff to. I know the stuff wont get me any power, I really want it to idle smoother.

 

you will be supprised if you change the diff fluid and pack the front wheel bearings

less rolling resistance= freed up hp

no one wants to flush the brake fluid but they cry when the calipers stick and wheel cly leak so just gravity bleed them out and presto less problems
