TTI Dougs with black finish

I have the TTi ceramics on my stroker. Easy install, and I don't have a rust problem after one full year. I had an oil leak that stained them and I freaked out, but I fixed the leak and the stain burned off in ten miles. I did have a few minor fitment issues with the steering, but moving the engine in the mounts made everything clear. I went from a 318 to a 408 - I blamed that for the fitment.
