I fitted one to my 1992 4/4
CVH efi engined ....
As the car was in need of use due to previous owners doing low miles I am unsure if the filter had an effect on performance or just the car responding to use generally, and a loosening up effect.
I think the original filter was from a Rover engined source.
I simply measured it and found the same dimensioned K&N as a repalcement.
