Not for 3V
Does not fit 05-10 Mustang with 4.6 3V. It’s not only a confirmed fit on Amazon, but also AI said the part number matched. Installed it today and while it bolted it up it didn’t seal like it should. Then the car would misfire heavy immediately on startup, and stall. Put the old one back in (that’s held in with tape. It’s a project car) and it was back to normal. Don’t know how this product works for others but definitely don’t buy for a 4.6 Mustang 05 or later.
