Quick and Easy Install on my 24v E30 Swap. Can be installed with a motor in the car without issue.
Perfect fitment easy install and no worries about coolant seeping out the the back of the cylinder head
Very easy to install, comes with everything you need which is nice. I added the extra plug for the lower line which was worth it. Seems to work very well but I have yet to put many miles on the car.
Comes with everything you need, including shorter than stock bolts. Nice material, Very quality
This is an awesome complete package with nicely machined plate, gasket, and proper length bolts. Big time saver and cleans up the heater delete clutter.
This blank off plate fit perfectly and is robust enough to hold back coolant pressures. Installed as part of a heater bypass mod for my E36 track car. Drove Road Atlanta hard for two days in July! No leaks. Installed with provided gasket only, no additional sealer as I intend to convert back each winter. Good product.
Install is easy. The fact a gasket and new bolts are included is nice touch. Installation is easy took maybe 5-10 minutes.
The plate is shown exactly what is on the website. Product was delivered in 2 days.
I purchased this block-off plate for a track build. The piece fits nicely and follows the contour of the engine well. It comes with the gasket and new hardware, which was a plus. Haven't ran the engine yet, but I don't expect any issues from this part. Fast shipping.
