Oil cooler Air vent

As the old beast is 21 years old! The late 80's and early 90's honda used a small oil radiator for cooling. Later designs got rid of the annoying pipe work and instead used a cooling device around the oil filter......like a water jacket. It saved on pipe work, I guess it made the oil pump more efficient, less umph to push it through the Metre or so pipe work. I guess thats engineering progress but I'm stuck with it, it works so Ive soldiered on and created my air vent duct from a ford air intake(previous post), fixed it into position with an aluminum bracket. The tricky bit to do was to measure and cut the front hole. It had to be slightly smaller than the plastic vent so not to look untidy................................ Job done!
