I know a lot of you already have air intakes but other than my sound system, this is actually my first real mod and it kicks ass! I got a 77 series K & N for my 04 Silverado 5.3L. At first I didn't think I would be able to tell the difference, but as soon as I put some gas on, it sounded like I installed a muffler under my hood! Man, you can really feel the difference! Also I noticed I'm gettin like and extra 1-3 MPG depending on where I'm driving. I was so undecided on which air intake to get for the longest time but I decided that 200 bucks for a brand new K & N intake wouldn't hurt my wallet that bad. It was pretty easy to install too, it only took me about an hour. This is so awesome. I have a couple of mods on the way, magnaflow exhaust, billet grille, SS body kit, and tail lights, I can't wait!!

What kind of mileage are you getting? I find it hard to break 17.5 mpg.

18 MPG easy, and I'm not exaggerating at all. 19-20 on the freeway at about 70-80 MPH (I live in San Diego)... Could be more on teh freeway but I ahven't taken it on a long trip yet. The biggest diefference is the city driving though.

my understanding is that it may NOT fit the 05 5.3's. the reason is due to the new design of the electric fan. i heard that the routing of the heater hoses is different than the 04 and lower years and therefore k&n for ex. had to redesign the intake because of this.

 

i believe this to be true because there still is no FIPK or 77 series intake listed on their site.....only a 63 series

Have you done anything else to your truck besides the air intake? I added a K&N to 2001 truck and noticed no difference. But i was wondering how will it do on the 04 with 5.3. Also are you getting a combined 18 mpg with city and highway driving?

Nope, that was my first mod. I just put a new exhaust on the other day though so it's hard to tell what my MPG is lately because I've been hitting the gas pretty hard trying to crate enough noise to wake up the dead. But before that, it's averaged out to 18-19 MPG combined city/highway...

I'm amazed at the MPG you guys are getting with teh "fuel efficent" vortec lines.....my brother is getting over 18 in the truck I used to have. and it hasn't had a tune up in 3 years!

My "fuel efficient" Vortec gets 13.9mpg.

 

My "not-so-fuel efficient" TBI 350 gets 15.5mpg.

 

I drive them both identically...So take that for what it's worth.

 

I've also never had any air induction kit make a whit of difference in HP, or fuel economy.

 

But I was born on the 13th...So it may just be me.

Yeah my 5.3 would only get 18 if I was going downhill and had a freaking tailwind doing all the work...ha. Course since most of my driving is city driving, its more like 12 mpg...

I've got the k&n Intake on my truck along with the other mods in the signature below and I just took a trip to the Smokey Mtns. from WV and that's pretty hilly all the way there. I made it down on one tank of gas and got 19.5 mpg Since I put the computer in mine I'm averaging 16 in town mileage. Boosted it 1-2 mpg all and all I think with all the mods.

I have a unmodded 2003 1500 with a 5.3. Almost 60,000 miles on it.

I get 17-17.5 MPG city and highway.

 

Just tossing out these #'s for craps and giggles.

Mines around 12. I drive city though. I would only get around 230-250 miles to the tank. I did get 350 on the last one. But that was on a 45 minute trip to and back. So there was some good highway mileage.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Why don't I have a good scanner? I've always wanted one when I've needed one.   My latest reading says I don't need to do a relearn on the ckp sensor on a 1995 with OBD 1.5. The relearn is prescribed for the later-model 1995's which shipped with actual OBD II when GM completed the transition in prep for the 1996 MY. I need to confirm that. Did you know forums are disappearing? Knuckleheads on Facebook... it's not the same. It's just not.   So, scanners. Again, shooting myself in the foot for having eBayed my Snap On MT2500 "brick" with all the adapters. Not that I couldn't buy another but those are getting quite old, and mine wasn't new enough to work on 2000's vehicles.   Damn it (as I'm scanning my email between paragraphs here). Did you know there's a 2000 Jimmy 2-door on BaT that's ending this morning? It's local. I want it. 14k miles. Absolutely beautiful.   Back to scanners. MT2500's are old. Solus, now that could be a contender. There's a ~2008 Verus with a system error that's basically new in box for cheap. Hmm...I'm not sure about a scanner that runs an archaic version of windows (95 or CE, I can't tell).   I want the ability to reset and rotate TPMS, test individual modules, bleed ABS, electronic parking brake controls for servicing brakes, relearn procedures and other bidirectional controls.   Snap On does an MT2600. It's a new model as of last year, marketed as their "entry" scanner. Entry? Only where $1900 gets you through the doorway plus, I'm guessing, $1000/year if you wish to keep it current. So goes scan tools actually designed for production environments. Want decent products with excellent support, you pay for it.   Everyone is raving about Autels and TopDons and Foxconns and all these newer brands that are selling the $500 "prosumer" scanners for backyard hacks like me. They're tempting...honestly. Updates are cheaper, base prices are remarkably cheaper... And you get to deal with bugs and translation whoopsies and, well, just don't use it on anything expensive, OK? Having a dealer replace an ECU because it needs to be re-imaged after an adventure in scanning is no joke. But I think most people are getting by OK with these units.   eBay on a scratch-and-sniff pro-model oldie, a shiny new TopDon, or???   God dang it, I can't stop looking at this Jimmy. I'm ready! I'll Bring The TRailer! It's beautiful.

      What have you done to your K2 today?

      By Texasdeere · Posted

      I removed the OE running boards.  It looked so much better.  I wish I took them off a long time ago.     I had to put something back on for my wife.  I wanted Westin Sure Grip Running Boards but they are very pricey, like $600 plus.  I was going to go with the Ionic 41's like I had on the 2019 Silverado but went with Westin Outlaw Drop Steps instead, about $200 cheaper.  They are sturdy and functional but not super crazy about the look, but it works.

      Disable DRL's

      By fondupot · Posted

      I had a Gen5DIY DRL relocate harness from a 2022 1500 that I saved. I had Gen5DIY modify the harness for my 2024 Silverado 2500. Plug n Play, worked perfectly.    Here's a video I made for the 2022 1500 truck. The install is more or less the same on a 2500.    The harness relocates the DRL tot he top amber turn signal on my 2500.

      Can ask that about a lot of places.   Holiday sells 91 for $1 over 87 octane. BP 93 is 80 cents. Amoco 93 is 80 cents Kwik Trips is $1.20 for 92 or whatever they have and $1 for the 91.   I know that this is not exactly same as what you are saying with the premium to premium debate of those two stations but why is there such a difference. Top Tier this and that, it's all BS. All the fuel comes from the same damn refinery, so give me a break.
