Just what the title says wondering what others have used and their effects.
Pretty much the cheaper parts due to them needing to be changed in the colder climates yearly or so thanks to Gms poor deisgn and the corrosion after a year of use.
The Vortec ones that bad? My first one. My ole HEI went for years
Yes it is a poor design, and those of us who live up here in the cold/wet environment go thru them. They need to be checked every spring. and dont be surprised if they are that corroded. that is why most GM guys agree that once a year change, though you may get more time.
Check out Performancedistributors.com, has what they call a Vortec Firepower Ignition Kit.
I went to this website. It sounds nice but no listing for the 5.3 's.
The Firepower kit will take care of it? Any performance gain or just reliability.
GM 5.3 liter engines do not have a cap and rotor. They have 8 coils and 8 short plug wires.
Unless you have some massive power adders on the motor you wont notice any performance gain since the factory ignition system can handle alot more than what your stock motor requires. However it does allow for more reliability. Which in your hunt for milage will help since it wont wear out as fast and will help you maintain the same milage longer.
aloxdaddy99, Blacksheep1 has a '99 4.3 V-6 Vortec, not a 5.3.
