GM 5.3 L83 & 6.2 L86 Intake Manifold Swap 2014+ (Complete Guide)

[@agp9844]

I did this with throttle body headers and dyno tune made major differences

[@Mel7eds]

I heard just a tune can wake the trucks up substantially vs no tune

[@TheMrmmkkpro]

Came across this video as I am searching for help doing AFM delete 15 6.2 silverado. Excellent work, direct and to the point with very pertinent information. Subbed. 👍👍🏁🏁

[@conklinb1977]

Hp tuners also has a spot for the volume of the intake that prob needs changed on the GEN V 5.3

[@xandersmith9832]

Thank you for putting good educational info out there

[@AaronHinesAuto]

Glad you like it! Thanks for the support

[@96tahoe2dr4]

​@AaronHinesAuto just outta curiosity can u put an L8T intake manifold instead of a l86?

[@buddyrebel_Garcia]

@13:52 I didn't change the 6.2 intake, it wasn't even that much of a hassle. All I did was put some lube on the inner of the 5.3 intake and with a flat screw driver slipped in the 5.3 intake into the 6.2 throttle body. No need to to waste more money when it isn't even a hassle. But good video.

[@chronicmat5787]

great video i’m young and this helps a lot blessings !

[@johnlundquist4846]

this video is so helpful. so much good insight and explanation! used your links to purchased the l83 intake! rock on buddie

[@TheJishwa]

i been looking for video like this awhile thanks for help

[@AaronHinesAuto]

Glad to hear, thank you!

[@TheJishwa]

@@AaronHinesAuto do you think I could c8 engine cover on manifold?

[@arcamediuas]

Nice video, very informative. Do you have any input on values for throttle bodies larger than the 95mm? Do you think a L86 manifold can be ported to fit a 103mm throttle body, or do you think anything more than a 95mm we are at the limits of the manifold?

[@davidcarr4464]

@ Aaron The last thing you want to do is run the engine lean, I get it. I don’t think the 6.2 intake and throttle body would make that much of a difference. I think the oxygen sensors along with the MAF sensor would give the ECM enough info to pulse the injectors on a little longer. I mean its always looking at short term and long-term fuel trims so you think if the 6.2 intake/throttle body swap made it a little leaner, the ECM would adjust for that. Your thoughts.

[@ryanakey1599]

You are correct the ecm will accommodate and adjust with just the l86 intake manifold l86 Tb and a 3.5 inch cold air intake it will adjust its self and no lean codes are thrown. I just did the swap this week and no lean codes no tune.. the map on the l83 and l84 are rich enough to accept the l86 swap

[@JoseAvila-le7dr]

Thanks another for you helping videos, aney help on removing a seized intake manifold on a 05 titan.

[@clifford2slow20]

did my l86 tb and Intake manifold and I started having a bad misfires in 3 different cylinders

[@choklo187]

Will I gain more hp on my 2012 5.3 if I put an intake manifold from a 6.0 or 6.2 of the same year range? If so how much? Is it a direct bolt on?

[@LuisTorres-ft9nq]

you listed the lt2 manifold as the lt1? or am i confused

[@thatrealcarguy]

So I could use my Camaros LT1 intake on my 2017 5.3? I still have manifold and TB from my 2018 Camaro SS.

[@jruizh793]

Do you have a video on how to install the lt2 intake

[@Patzfan4eva]

If you have added a edge CTS3 programmer, cold air intake and cat back exhaust, any advice on tuner changes needed to maximize this modification.

[@hugodiniro]

Any work to the fueling side ? Since air was adjusted ?

[@quintenbrown1508]

So do I need to buy a 6.2 cold air intake

[@j_rod75]

I did this swap and have not had any tuning. I have noticed harder shift at times from 2nd into 3rd, mostly when getting on it. Is this because of these air volumes being to low now?

[@flowmagic5]

I’ve been hearing this and I’m about to do this same thing to my truck! But is ur truck running good? Only whe you get on it it shifts hard? That might be because of the amount of air that now is getting for sure no big deal bro

[@j_rod75]

@@flowmagic5 I don’t think it has anything to do with the bigger intake now. I put my stock intake back on and it still does it. I’m debating putting it back on but if I do and decide to spend more money I’m getting a tune at the same time.

[@jaycastillo9313]

At the end of the video you say “And continue with any tuning you need to do” is there anything else that needs to be tuned with this swap or just the airflow parameter being increased? Thanks.

[@jayer-su3hu]

Can anyone tell me if this is a "plug n play" swap or will my ECM need tuning afterwards?

[@alexvarela9154]

What up Aaron... quick question???? What your opinion on oil catch cans...

[@michaelgabert4261]

If i swapped to the l86 and upgraded to the jet 76116 performance throttle body should i switch the air flo sensor to either the jet 69180 (which i think is for a 6.2) or jet 69189 (which should be for 5.3). Thx in advance, great video. Convinced me to do the swap, lol.

[@christopherbrockway2035]

What kinda tune do I need to do this swap and how much is the tune

[@morganpayne5404]

I’m about to do this swap on my truck. Did a DOD delete and stage 2 cam from Texas speed already with High flow cats and cat back exhaust. Will the stock intake manifold cover still go on the new l86 intake? I saw you didn’t put it on and I’ve assumed it won’t fit but I’m just curious. I haven’t read all the comments so this may have been asked already.

[@Mel7eds]

Apparently it does fit per previous reply to another comment asking. Hopefully they’re right and hope it works for you

[@pedrocollazo4437]

How is it running with the stage 2?

[@mad_max2065]

Badass video

[@AaronHinesAuto]

Thank u!

[@timharris4249]

Aron, I don't have a cam but my exhaust is modified headers, no cats with maxiflo. Will the Lt2 help me or Lt1 be more practical?

[@bigohubcity3159]

what was the torque specs for the throttle bottle bolts?

[@mrarmy300]

Wow, very thorough, thanks for sharing! Are you aware of any intake I can swap onto my Gen IV 5.3?

[@VAlien79]

Any reason my l86 intake manifold would have a extra vacuum port on the drivers side on the back towards the firewall? I did the swap everything bolted up great and noticed the port was causing a lean fuel trim. I plugged it with a cap and everything runs fine now and no CEL or codes?

[@theborderboyz]

My l83 has that port you’re referring to. I know it’s a year late but I would confirm it’s in fact an l86 intake

[@VAlien79]

@@theborderboyz thanks for the reply! Do you have any lines going to this port? Or do you have it capped off…. My original l83 that I took off didn’t here the port and the throttle buddy opening was smaller then the one I have on now.

Man be careful torquing the intake manifold bolts my torque wrench only went down to 10ft lbs the bolts call for 8 ft lbs I figured it would be fine I ended up snapping one off at 10ft lbs had to get a die grinder in there and grind it flat drill it out and use an easy out to get it out

[@ryanaustin1970]

putting either the LT1 or LT2 intakes on a truck is NOT a performance improvement , it is a down grade . you make less torque and gain very little horsepower , considering trucks and suvs need torque to move their fat asses they need all the torque they can get . a huge improvement is custom tune , CAI , ported L86 intake with ZR1 throttle body

[@ryanaustin1970]

also ABSOLUTELY do not need to tune or relearn anything going from 5.3 to 6.2 t.b ...i did it , zero problems , now if your were to buy ICT billet adaptor and run a ZR1 throttle body then yes it would need to be done . youre forgetting these trucks tend to run a little "fat" on the air fuel ratios
