I am going to have the intake manifolds worked on for my 03 Mach. I was wondering if anyone has any experience between PHP's Mach intakes at $1,200 vs. Extrude hones work for $600. PHP port and polishes theirs for the extra $600. I am sure both companies are quality but is there that much HP...

Has anyone come out with perf. heads yet for the Machs? I was thinking the mach could stand to pick up a few HP with heads....port/polish etc. I am trying to hit 400 HP naturally aspirated....it will be a challenge! Thanks! :flag:

The only down side I have ever heard is the "drone" might be a little louder with 4.10's when your on the highway....personally that would be music to my ears!

I have been sticking with Motorcraft 5-20W synthetic blend too....when I can find it on the shelf!
