When you replace the timing set (also a weak point), use the SRT chain, gears and tensioner. Has 2 chain guides and a better springs, for those guides. Plug and play.
Copper plugs. Nothing fancy necessary and would be a waste of money. Super easy to change, compared to the Hellcat.
Taylor "shorty" wires clean up under the cover. It's a rats nest, with all those long wires crossing over the intake.
LMI makes an amazing CF intake called the Air Hammer. Sounds great on the 5.7.
If you have any lights out, in the climate control, I can fix them. Same, for the radio. If it has heated seats, I can fox the bulbs in those buttons. Almost assuredly, the hazard button light is out. I can fix that, too. All other lights are led and rarely fail.
The visor clips fail. There is a Corvette clip everyone uses, to replace them with. More robust and plug and play.
The radio can be upgraded, with a higher end oem model. Simply plug and play.
Headlight switches fail, all the time (gen1 charger, 300, magnum, jeep, challenger). Just buy a new one. Even a Doorman works fine.
As has been mentioned, blend door motors fail. OEM. Doorman ones are garbage.
We had ours for 10 years. 2005 RT.
