Extrude Hone Porting in San Francisco CA

Enhance the performance of your engine with extrude hone porting in San Francisco CA

If you are a gearhead, you are most likely already familiar with the benefits of porting intake and exhaust manifolds and other engine components to enhance fuel and air flow. But can you name the number one method for porting?

Hint: it’s not hand porting, as many DIY sites suggest.

It’s extrude hone porting in San Francisco CA.

AFM ProcessExtrude hone porting, a process which was pioneered over 30 years ago by Extrude Hone AFM’s founder, has since become the process of choice for all kinds of engine enthusiasts. Today it’s used by OEMs like Cadillac and Ford on their top selling models, and it is also being used by hobbyists on

  • Racing engines
  • Muscle cars
  • Motorcycles
  • Personal watercraft
  • High-performance trucks

How Extrude Hone Porting Works

One of the biggest limitations of hand porting--besides the incredible level of skill and control that is required to abrade the metal evenly--is that it can’t reach deep into the twisting passages of a manifold or other part. Extrude hone porting in San Francisco CA, on the other hand, can reach every millimeter of all sides of any passage. In extrude hone porting, a putty-like polymer media loaded with abrasive grit is passed through the passages in a manifold under pressure from a hydraulic ram. As the polymer runs through the part, it becomes a flexible slug that sands away material evenly on all sides of the hole or passage. Our polymer media will flow through countless cycles without clogging or separating. Fresh abrasive particles will constantly recirculate to the edges of the media, so you always get even honing on every exposed surface. The process can be controlled with a high degree of precision to ensure that the porting gets done to the exact specs you have calculated will enhance your engine.

Benefits of Extrude Hone Porting in San Francisco CA

AFM ProcessAFM ProcessAny passage that fuel or air flows through can benefit from extrude hone porting in San Francisco CA. The biggest improvements in engine performance are seen from porting the manifolds, but porting can also improve engine heads, turbo impellers, housings and pumps, and 2 or 4 stroke cylinders.

The result of the extrude hone porting process is increased flow velocity, not flow volume. Combustion becomes more intense, encouraging:

  • Increased horsepower
  • More thrust
  • More torque
  • Increased fuel efficiency
  • Reduced emissions

We can’t make specific promises as to how much more horsepower you’ll get or how much fuel efficiency will improve after extrude hone porting in San Francisco CA, because these end results depend on your specific engine configuration. However, you can expect to see up to 25 percent increase in flow after honing an intake manifold, which will give you an idea of how much performance will improve.
