Thread: K&N air filter

There is some useful opinion on the K&N type filters on this page from a Suzuki Forum. auszookers.com • View topic - Air filter rant (I also have a Suzuki.) Anyway, I only use paper filters now.

The K&N always came out at the bottom for filtration - by an alarming amount, and the particulate size they let through was scary.

No 'I think' or 'a mate said' - actual scientific testing. There are plenty here that have seen tyese results - it would change your mind in a flash.

I think a well maintained, cleaned but used OEM paper filter scored best for actual filtration - better than a brand new one.

I'll fire up the laptop soon and link to Ben's tests.

Real and repeatable data can't be beat.

Better late than never Air Filter Tests (Finally)

If you really want to know how a K&N performs, read these test results. They are real tests using properly calibrated particle testing machines in the filtration testing lab at an Australian university.
Not "I think", and "it feels", and "it looks like".....

Yeah, but still. I feel, and it does look like .....

thanks very much for all of the opinions and info on this subject!! outstanding facts seem to be stay away ... cheers everyone

Mate, jump online and buy yourself a service kit from the UK. Whether you go for genuine Land Rover, premium aftermarket or cheapie is a matter of personal preference and philosophy largely, but it’s a cheap way of doing some basic maintenance that’ll protect your car in the long run.

I change my oil and ALL filters every 5,000. That’s overkill — WAY overkill — but if I’m dropping the oil and changing the filter, I may as well change out the air and fuel filters too.

Clean oil and fuel will go a long way to looking after your diesel. Cheap insurance

I thought the message from isuzurover's test was that an air filter works better with a bit of dust on it. A clean one lets more dust or bigger particles through.
