We spent a year and a half testing and tweaking the design of the LFX Extendolator intake manifold spacer. After several rounds of dyno testing, design changes, and trying different thicknesses, we are proud to offer this product to the Camaro / LFX community.

Key benefits include:

•Up to a 7-10% increase in low-mid range torque, and a 4-6% gain in low-mid range HP.
•Cooler intake air temps can be realized by lifting the intake off of the hot engine.
•More low end power/torque means the engine doesn’t have to work as hard to get the car moving, which could potentially result in increased MPG.
•Reusable. No need to deal with messy RTV sealant, our spacers are CNC machined to accept OEM GM o-ring gaskets, which are included with each spacer. Goes on easy, comes off easy with no mess to clean up later.
•Made in the USA


•Q: How does it work?

•A: The power band of an engine can be directly effected by changing the length of the runners in the intake manifold. By lengthening the runners, more bottom end, and mid range torque and power can be realized. In this case, adding the 3/4? thick Extendolator Spacer shows a NICE gain of up to 7-10% in torque up to 5,000 RPMS, and a 4-6% gain in low end power.

•Q: Is it available in different thicknesses? Why 3/4??

•A: Currently, there are no plans to make the spacer in any other thicknesses, although upon special request we can probably make one for you in the thickness of your choice. Some pretty extensive testing has taken place over the last year playing with different thicknesses and the 3/4? was determined to show the greatest low to mid range power gains with little to no sacrifice in top end power.

All spacers include new proper length intake manifold bolts, longer hardware to attach the lower intake manifold portion to the upper w/ the spacer, new GM o-ring gaskets, and FREE SHIPPING INSIDE THE LOWER 48.

Excellent Upgrade
The JacFab intake manifold spacer works very well with the LFX motor. I noticed a decent improvement in overall throttle response on my Camaro with this product installed.

Great product
Pairs up nicely with the ported intake. Paired together you get a nice boost all the way through the RPM band. I'd back Jason any day with recommendations. Great products with superb service. Not to mention this and the intake are duper easy to install. I've had mine on since late spring, and would purchase again in a heartbeat. Thanks Jason!

I noticed the gains right away fixed all the lfx torque issues. The car slams me back into my seat now. Definately the mod the i noticed the most gains from. Now i just need the laminator fx and see how well that pairs up with it .

Improved torque
Extendolator is the real deal and worth installing. I notice torque gains on lower rpm, better throttle response. I recommend tune for better performance.
