High Performance air filters

[Gnarly Dude]

We have been suffering problems with our motor ever since we took in a little bit of sand through the snorkel, turns out all the pistons have been sandblasted and the valves will probably need replacing. What filters do people run on their trucks and what do people think of them? We were running a finer filter and it was the wrong size and pretty hopeless. It is a carby 231 Buick V6 with a top mount air filter running to a snorkel.

Thanks

was the filter not seating properly mate?

I use a filter before the hat, filter foam cut to suit but uni filter do them and a filter sock inside the snorkel and a k&n Apollo closed air intake system. Works well for me clean filter regulary but hardly gets dirty.

Coz you asked mate

the setup you've already got sounds pretty good albiet needing to stick the right size filter in there so it seals up and keeps all the big bits out of the engine

I used to run an open 14x4" K&N filter with an oiled foam prefilter over it on my flatdeck with bad results, I was always finding shit going through it and it was always a big mess when you added mud into the equation so I went away from that and went back to the standard toyo airbox and snorkle with an oiled finer filter in it and although it was more restrictive and not as free flowing as the K&N the truck still went like a cut cat and I had good reliability keeping shit out of the engine, it all sealed up tight and if you took the ram off the top of the snorkle and blocked it off with the palm of your hand the engine would die instantly as if you just turned the key off, its not a recomended practise but its a good way to see if theres any air leaks






My 40 series cruiser came prebuilt with an enclosed aircleaner housing on it with 5" ducting through the firewall drawing air from inside the cab, its not the perfect setup, it clamps down tight and has good protection from water and mud but its definately not up to submersable standard and you tend to suck a lot of dust out of the cab on gravel access roads etc, I just use standard paper filters in it and keep and eye on them change them whenever nessecary, they get a hard life and seem to work ok they always stay clean on the inside. I've gone away from K&N's and any high flow filters for the 2-3hp difference I'd rather have the security of better filtration and less shit getting through engines start getting expensive when you keep fawking them Thats my 2c worth not everyone agrees and some people still swear by high flow filters and all that shit but each to their own

Theres a few other threads about filters on here with varying opinions on the subject and I would have posted all the same shit and pics before




That was a brand new paper filter that did 1.5 days at Gwavas last year

I used to run those foam filters and got the same results as Sadam_Husain...
So ditched it and went back to paper ones... Didn't notice any difference in performance but did it catch some s*&t.
They might be fine for round town driving, but off road ??

You cant get better filtering than the factory paper type.
I run factory paper but have a foam droopy in top of the snorkel ,,this stops all of the bugs,sticks , leaves etc getting into the snorkel & also most of the dust getting to the main filter.I wash it out then reoil it after every trip.
Some will say having both will loose a little power but if it does its bugga all ..id much rather have clean air than 1 extra horsepower.
