GEN.7 MODS STOCK & TUNED
(2008-2012) Chevy Malibu
2.4L Ecotec ( LE5 )
| LS, LT, LTZ |

Non FlexFuel, Non California Emissions

Hey y’all wanted to start a fun thread and just share some fun mods for the 2.4L LE5 don't matter if y’all are stock or tuned just here to share fun ideas with y’all and see everyones setups🤘🏻

Everything but the LTZ Swap stuff which everyone can find on eBay as I did I’m sure lol everything else is all from

zzperformance.com

it’s all under the Ecotec category y’all should be able to find it just fine!

AIR INTAKE UPGRADE
An easy day one mod is to ditch the stock Ecotec Engie cover/intake they never deal correctly and are annoying trying to work in the engine bay, either make your own from the parts store or order an after market intake, ZZPerformance makes a really nice high flow intake tube just for the 2.4L but idk if I can justify the price when I made the same thing for $30 tops lol
70345

Now this next one is a must if you plan to run like a K&N pod filter style later down the road your gonna need something like this to adapt the GM card style MAF Sensor into your new intake

70346

Engine cover from a 2.4L Ecotec Equinox, if you want to have your custom intake but still want your engine to look stock, or you just don’t want to see the 2.4L bare this is the way to go! I found this one on eBay, just ordered this for mine while I was making this lol.
Factory 2.4L Chevy Equinox Engine Cover
($45-$65) eBay

70383


IGNITION SYSTEM UPGRADES
The next mod I would probably do after this is get a set of these ZZP high voltage coil packs and a fresh set of ACDelco Iridium Spark plugs, My car is tuned and the 2.4L loves the Iridiums from Delco. Do not buy NGKs car did not like them I cracked 2 of them surprisingly one day.

Perfect way to finish off the ignition system with this sweet coil cover plate from ZZP is literally just cosmetic but it really dresses the engine up big time I think!

SWAPPING LTZ PARTS ON (LS, LT)
Another sweet mod that I’m in the process of doing currently is swapping my stock LT red tail lights out for the Clear lens LTZ Tail lights. Pair them with a set of Red LEDs and it looks awesome, Also adding the Factory LTZ Fog lights will run ya about $250 I swapped em into my LT with H11 6K beamtech LEDs

Pair of Factory 3.6L V6 LTZ Outer Taillight Housings
($190-$225) eBay


70349

The next best LTZ parts swap is to find the stock LTZ 3.6L Dual Tip Muffler and the Factory 3.6L Dual Tip Rear Valance

Factory 3.6L V6 Dual Tip Rear Valance
($75-$80) eBay

70350

Factory 3.6L V6 Dual Tip Muffler
($170-$190) eBay

70351


LSJ Throttle Body Upgrade
I am not 100% sure if you need an hptuners for this one or not but essentially it’s a LSJ Throttle body and adapter from ZZP because the stock LE5 Throttle body is small and actually restricts airflow. Into the larger intake inlet.

70352

70353


Very cool upgrade actually I’m gonna have to try this out for sure, feel free to post any mods y’all want I love comparing with y’all! Dont be afraid to PM either with any questions y’all might have thanks again!

Yes to the taillamps! Did it to my 2LT during it's LTZ transformation, and they look great! If you get lucky, you can find good condition, used housings on eBay. If you get even luckier, you can even find them with the stock bulbs. I got mine for $59 plus shipping. Only thing is, on the stock bulbs they do require a different harness, but it's essentially plug and play to get it in.
Part number for the harness:
25913257
In my honest opinion, it's worth the hassle of getting the new harness installed for the factory bulbs. You get the clear bulbs in the clear housings, plus if you use regular 3157 bulbs, you'll need to cut the housings too...

Very detailed writeup, hats off to you!

I have the 3.6 rear bumper filler and custom dual exhaust, I’m currently waiting for the rksport one which gives it a more aggressive look. Here’s my setup and upgrades I’ve done.

I take it the modified intake and cat-less exhaust required tuning. Did you do it yourself with HP tuners? I'm trying to figure out if I want to go that route with mine.

The modified intake no you do not need a tune you can run the factory air box with the custom intake pipes on the stock tune, if you end up running a pod filter setup then yes you will need to tune the MAF. For the cat less setup you definitely need HPtuners in order to disable all the downstream O2 and emission codes. I love mine and I highly recommend it!
