D13 manifold

For the short time I've had it installed it's made a notable difference. Granted, my previous OEM manifold was cracked in half so I would expect no less. Got to run it for a week or so and noticed it was pulling hills better and temps were slightly cooler. Dealing with a cracked EGR cooler now so long term results and any fuel savings is yet to be determined. Side note: the manifold looks fantastic with the polished ceramic coating. So far I'm pleased with my purchase at the very least.
