  1. I'm sorry but this is not the right part number. I was told wrong!
  2. I'm looking for a part number for the power cord that plugs into the outside of the truck. That runs the block heater. The truck is a 2020 3500 HD High Country with a 6.6l diesel. They bought it used and it didn't come with it. Any help on the part number and/or where to get one. They used to go to Florida for the winter. Not this year! Need to be able to plug it in.
  3. The factory prep punk mount is made by Curt. I have heard others ordering a punk kit from Curt. And I know that some had the dealer order and install in their Silverado.
  4. I just installed this K&N 77-3103KC and I have only drove it just a few miles. Doing a trip later this week. But I am thinking of enclosing the filter box, so it only draws outside air. This only replaces the top hid of the OEM air box. K&N Cold Air Intake Kit: Increase Acceleration & Towing Power, Guaranteed to Increase Horsepower up to 20HP: Compatible with 6.6L, V8, 2020-2021 CHEVROLET Silverado 2500 HD, 77-3103KC https://a.co/d/0tSCKGq
  5. Don't know how much this will help. But anytime you can get more air flow. It's got to be better! Now on to my next project. A cold air intake upgrade. I'm going to use the OEM filter box and just put a tube in.
  6. I asked in a thread Cold Air Intake if anyone seen the Stillen replacement Air scoop. Well after looking at their replacement scoop. I just modified my OEM scoop. Didn't think I wanted to spend over $250. So I modified mine kind of to be like theirs. In the area that goes to the filter box, there's a little wall. I removed it. Then I took the scoop out of the truck. 9 pop pins and 2 T15 torx screws. And seen that they only had half the front opened up. So I cut the flap off and open the other side. Then reinstalled it. Here's some pictures.
  7. I don't know about being a younger one. I turn 64 next week. Somedays I like it's going to be 84. One thing that I have been learning is that the OEM mufflers no matter what make. Are one of the main reasons exhaust Manifolds Warpand break bolts. Causing too much back pressure.
  8. I installed the AFE system. And after adding a resonator muffler, it's better. I like what it has done. Better throttle response and fuel mileage. Still has some drone in the 1500 to 1800 rpm range. Sounds good when pulling the rv. If I had to do it allover again. I would just change the OEM muffler. Walker's Dynomax 17517 and you need a piece of pipe. Walker 43366. I found these on Amazon. There is also Magnaflow 12909 Flowmaster 953558 and 74151. These are all 3.5" inlet and outlet.
