Motorcraft EV297 Valve Review

As a result of my tests, i determined that the Automotive valve I purchased far exceeded my expectations. Its high-quality construction allowed for optimal exhaust flow and a noticeable improvement in engine performance. The durable design ensured it held up under tough conditions, which is particularly important for off-road adventures .However it was slightly more expensive than other options on the market. Nevertheless, the valve was well worth the investment for the superior results it…

If you have Ecoboost you need these check valves! I've included the factory in my photos for reference which are just through. The new check valve connects in the same place as the factory one, but provides a non-return system to avoid 'pushing/vacuuming' your crankcase. It's of course amazing why Ford didn't fit them from the factory, but when combined with a catch tank your Eco will run as cleanly as possible without creating sludge! 15/10 recommend
