K&N Air filter on a 5-cyl diesel engine?

[3246cc]

I was wondering does an K&N air filter will increase any performance and sound on a diesel engine (5-cylinder).
I question this because I had an gasoline engine with this brand and in made a-lot of sound, better throttle respons and a little very little fuel economy.
Thanks in advance

No absolutely not. Never put a K&N or any low efficiency air filter on ANY diesel engine unless you use it for competive racing and there is an advantage.
