Fellow Formites,
I’m getting a Snorkel Fitted to my Paj next week and I was wondering if I needed to change the standard air filter for an aftermarket one say a uni-filter? Will/is their any benefit in doing it?

Thanks in advance

See forum notes on Unifilters etc - they can stuff up your sensors in the air flow system - (fine oil droplets) - throw up error messages on the dash and send the 'puter into a spin or sorts. With a probably cleaner air supply via your snorkel, you might well do to stay with the paper types.

If you don't over oil your Unifilter you'll have no problems. I ran one in an EFI petrol for years, I ran one in my Mechanical Turbo Diesel and I'm running one in my EFI Diesel. No Problems.

Thanks Gents,
I'll take a closer look at the uni-filter site and decide from there the best way to go, thanks for the heads-up about too much oil Banjo.

I understand that if you ask Safari this question, they will recommend paper filters only. I believe there are airflow issues as well.

Cheers
Phil

K & N also supply 4WD fitments for their airfilters. They use a cotton rather than foam and less oil.

When i had my disco dyno tuned the tuner said my finer filter was too restrictive at highway speeds and i should go back to a paper filter.
Foam filters are generally over oiled thus become more restrictive, but also let for dirt into your engine.

I have since read up on filters and would now only ever use quality brand, paper filters, see link.

Excellent read John,
Thanks for that I didn’t understand allot of it but I read the bit at the end re: the conclusion and I have made the Now informed decision to stick with the standard Paper Filter once again thanks for the info.
