This last summer in the middle of the great "E-Core" debates that raged I decide to try one on my new Ford F250 5.4L. In June at 1K on the odometer, I swapped out the factory filter (which was a nice Champ labs engine OEM) for a SuperTech ST-2 E-Core and used SuperTech 5-30 SM oil. During the 4K run on the filter and oil, I had no problems in start-up noise or any indication of problems with the filter. never a delay in oil pressure. Using a pnuematic cutting wheel, I slice the filter can open and pulled out the filter element. ADBV rubber was still supple. The filter element showed evenly space pleats and I could not even find the weld seam for them. My biggest concern was unfounded in that I found the fiber end caps very well installed on both end and took a deliberate effort to peel/remove them from the filter element. Center support basket was sound also. With this under my belt, I feel the E-Core design is sound in normal change intervals. I would not hesitate to use again or recommend.
