Greetings,

Sorry if the question has already been asked but does changing out the air intake to a cold air like K&N and putting a different muffler on the truck make a real difference?? I like the looks of it but I would like to improve my gas mileage. I have a 2018 1500 5.3

It all depends on how you drive. 

Aftrer I put on my Borla exhaust and an AFE cold air intake, I found it tempting to hear it. ?

i would say in the long run there is not much  noticible diference.

It likely wont change anything. Do for sound and/or just personalize your truck that way you wont be disappointed. I do it to every vehicle I purchase because I not into crazy modding. Just catback, CAI, everything else is just for appearance.

Biggest difference will be sound. Which leads to a (slight) decrease in gas mileage... Mainly because you're gonna be giving it more throttle than usual to show off that new tone.

The two together wont make hardly any difference.  The two together and a tune will make a big difference.

I know you asked about a cold air intake and a muffler together but this was pretty interesting to see. A real before and after with a cold air intake without the truck leaving the dyno.

Scroll down page a bit to see results of different intakes compared to stock

Also see the thread

So the video above yours, shows similar dyno numbers but on a 5.3... blackbear says their test was a 6.2? So how is that the case?

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
