Welcome to the FIRST® Performance Center website!

12-4-12  Update: The shop modifications are finally completed. The pattern repair is about 50% complete. Please remember to leave a message on our machine when you call us if we do not answer, as we are in the shop with air and power tools and cannot always hear the phone ring. Just leave us a message and we will return your call as soon as possible, usually in the afternoon. We are hoping to start taking orders again sometime in January 2013.

Attention:  As of 7/4/12, we will not be able to fill new manifold orders until further notice. This is due to major re-construction to our facility.  We will also be doing some extensive remodeling to our tooling for our First® TPI Manifold during this down time. Unfortunately this work will  not allow us to machine new manifolds at the same time that this work is taking place. We will update this as soon as we are able to fill orders again, which will be as soon as we possibly can. We are sorry for the inconvenience and if you have any questions, just give us a call.

The First® manifold is available for the standard small block Chevy head, Center bolt style head, Vortec, and NOW..... 

The FIRST® manifold is available for the LT1 motor for all of you LT1 guys that want to bring back some of that lost torque! You can still run a standard distributor! Comes with or without distributor hole.

Our company is based on the philosophy that a quality product that performs well should be affordable and still be able to stand the test of time. We have acquired the rights and tools to reproduce this great product that has been around since the late eighties when a company called Airsensors developed and produced this awesome manifold. We are in the process of creating changes that will improve this product and create an improved version for the 21st century.

We plan to expand the applications for this manifold such as Vortec head design and maybe in the future for Big Block Chevy, Ford, Chrysler, etc. We have tested this manifold and have been in contact with many others who have been involved with the design of this product and many people who are currently using this product and have had nothing but outstanding reviews. This manifold improves all around  engine performance and fuel efficiency based on our own personal results. We have Dyno tested this manifold on our own personal vehicles and we will post the results on this web page soon. Everything we sell on this web page, we personally run on our own vehicles. Our company does all kinds of fabrications and modifications on all types of vehicles.

We are trying to create the best MPFI (multi point fuel injection) possible.

Change that carb to mpfi tpi style manifold.
Great mpg w/Awesome power & torque
