Amplification: Was not thinking about the availability from the factory, was thinking about a major engine and transmission swap to create what the factory won't.

I really like this Spectre cold air intake, a noticeable gain IMHO. I have achieved my best MPG, 41.7 Imperial since running this intake. I am guessing 1 mpg to 4 mpg, depending on driving habits, unless my display is lying. My Hellcat lower box got lost in the mail, not bothering to get another one. I will be putting in the headlight plugs and stock box in for the Winter. I have the silicone adapter from the Spectre tubing to the stock box. Since sanding the edge of the tube, the filter hasn't come off. I wanted to put in the biggest filter possible and this Amazon dry flow filter fit, perfect fit and matches the car.
Well I am now at 131,000+ km. I picked up the higher end brake pads, got a bunch of dollars on my CT card. I may pick up a spare Continental serpentine belt. My last Challenger needed pads at 150,000 km. I will access when I install the studded Winter tires. I also picked up this off Ebay. I may do minor cleanup on the casting lines before installing depending on how it looks. It is the Performance Upgrade intake, better flowing vs my stock intake.

It arrived, looks good, not bad for just over $125 CAD. The only other parts I might consider are the 8 hole injectors, slightly better MPG, NGK Ruthenium spark plugs and Accel coils. I got the Autolite Iridium spark plugs really cheap a while back, I may change them alone if nothing else fails in the next few thousand miles. I'm sure the original plugs should be changed soon, 150,000 mile is the suggested, I may be an easy one later today.
Did an oil change today, 0W20 Mobil One Fuel Economy full synthetic. I decided to check one plug, .045" gap still at looked really good at 131,000 km.
Ground electrode looks pretty worn to me. I'd put them on my to-do list.
Yeah, there is some wear there, better than I expected. I believe the factory gap is .043", so only .002" erosion. I may do them when I put on the Winter tires. Of course I have pull the intake pipe and the upper intake to do them. I will be going back to the stock air box but leave the tube for the Winter. The Charger AWD under engine splash cover fit perfectly, it is different from the RWD.
Well I decided to do the spark plugs, got the Autolite Iridium spark plugs really cheap off Amazon a year or so ago. There was .010" worth of wear, definitely time. With the upper intake off, I could finally finish sucking out the mouse nest with the shop vac. Pretty sure it was from when this car sat on the dealer lot for a year. I tossed the 1/2 chewed pad under the upper intake. I used a shot of dielectric grease in each coil boot and a small amount of Permatex Cooper Antiseize on each plug thread. I used the piece hose to hand thread each spark plug. Everything torqued to factory specs including the spark plugs and gapped at .043". I just put in the head light plugs for the Winter and removed the mudflap I completely blocked off the coolant overflow from the air filter. Car runs great after the test drive. I also polished it with Tutle Wax and Meguirs Ceramic polish, both work on plastic.
