V8 Air filter type

Hiya guys and girls,
can someone please tell me the diff between twin K&N air filters and one of the saucer type air filter, which is preferred.
Cheers Scrump

dry filters are best.

K&N use filter oil to help catch dust and prolong the life of the filter - pipercross (I think that's the right make!) and greenstuff do foam only high flow filters that are not oiled - this means they don't mess with the MAF sensors. Really only affect hot-wire MAF and not so much the flap mafs on the early EFI's.

I assume that's what was meant by wet/dry? If not my apologies!

The 3.9 was a hot wire - the 3.5 efi's were flap MAF's. I use a K&N on my Camaro and it's a hot wire MAF - all it means is that you should spray MAF cleaner (or electrical contact cleaner) through the maf (when removed from the car) leave it to dry and refit. It's worth doing every service interval. You may find you get better fuel economy and performance if it's not been done for a while. NEver touch the wires!

Not all 3.5 V8's were flappers - Discovery 3.5 is hot wire on 14CUX ecu.
