2012-13 Impala Modifications from Overkill Motorsport

Here's a compilation of all the products offered by Overkill Motorsport for the 2012-13 Impala 3.6 V6, which also applies to 2014-16 Impala Limited (old body style).

:: Overkill Motorsports :: www . getoverkilled .ca / 2012impala.html



For the 2012-13 Impala, Overkill tuning is offered through EFI Live Autocal. This is an easy to use handheld solution which allows you to read, flash and scan your Impala without a laptop. You'll get a 91/93 octane and 87 octane tune, along with E85 tuning if yours is flex fuel equipped, improved throttle response and feel, revised transmission shift pattern and feel for a sporty comfortable drive, speed limiter removed and much more.

Most importantly, you get custom tuning at no extra charges. Not only do we have our own calibration revisions for our own 3.5" intake and MAF upgrade, 80mm throttle body upgrade, ported intake manifold, JacFab intake spacer and more, but you can also provide scans and get multiple revisions, all included in the $499.





Some LFX platforms come with an unacceptably small 3" MAF sensor, the 2012 Impala is one of those. The Overkill 3.5" intake increases the overall diameter of the system along with a new 3.5" MAF housing. This improves airflow greatly and is the only setup on the market that increases in size.

This setup also grows with you. I provide a new throttle body coupler and a new metal connection tube with a mild bend at no charge when ordering the Overkill 80mm throttle body and JacFab intake spacer, for a great fit.

A K&N Retrofit kit is also available, for those who have the K&N system already. This reuses the K&N air filter and shield, but replaces the tubing and MAF housing with larger 3.5" components.

Tuning is required for this intake and is sold at a combo discount when you order both intake and tuning at the same time, starting at $629.





Overkill is the only company offering a solution to the small 72mm throttle body. This a larger 80mm throttle body (measured at the throttle blade) that'll flow a lot more air. Improves throttle response and lets your LFX V6 sing at higher rpms. This kit specifically made for the 2012-13 Impala comes with our adapter plate, an EVAP solenoid relocation kit, all stainless steel allen bolts for a great look, and some items to help installation. No tuning required however those with Overkill tuning can get a no charge retune with improved throttle sensitivity calibration. Will not work with the factory intake tubing but works great with an Overkill intake setup!

Requires the use of a JacFab intake manifold spacer and is sold together as a discounted combo on our website.





Overkill is your exclusive source for the 2012-13 Impala specific intake manifold spacer made by JacFab. This spacer goes between the upper and lower manifolds, increases runner length and with it mid-range torque and upper rpm horsepower, as shown in this thread http://www.impalaforums.com/8th-gen-...no-tested.html.

An easy and effective modification that can be done at any point in your modification list.




Computer Tunes for all 7th 8th and 9th Gen Impalas including 3.6 Direct Injection V6, 3800 Supercharged V6, 5.3 LS4 V8 and 3500/3900 V6
