I recently replaced my fuel filter, did a fuel system cleaning, trans flush, coolant flush, power steering flush, replaced intake gasket and manifold gaskets. Also I use synthetic or synthetic blend oil with a fram oil filter. I'm at 106K miles I've always heard that doing a tune up on the 3.8 is difficult and what are the best plugs and wires to use and what's the best gas to use.

 

use regular gas with a 3800, premium if you are supercharged. AC Delco plugs and wires.

 

Thank you Chibi. What brakes and rotors would you recommend?

 

I like Centrix Premium rotors and Bendix ceramic pads

 

Stay away from Bosch plugs. AC Delco prefered, but I've also seen that AC Delco outsources to NGK. I've used NGKs in some of my GM v6 cars and ZERO issues.

Changing plugs on the 3800 non-SuperCharged are easy, just take your time.

 

Should change the coil packs too?

 

No, the coil packs don't need to be regularly changed until there is a problem with them.

My stock ones lasted over 185,000 miles and I never had a problem

 

Thanks Chibi and The_Maniac. Also I'm wondering if I can install HUD in my car?

 

You can if you grab all of the stuff from a grand prix, cut your dashboard, etc. It's really not worth it, not many have successfully completed that.

 

Like the ones in the high sport package monte.
I meant the driver information center
