air filters

are there any air filters recommended for the V8? its a flapper efi 3.5.

does the v8 need a very good filter or is it not to fussy?

the ranger rover one was very heavy so dont want to use that.

was thinking of using a standard car one like the rover 45 etc, and just putting a K&N replacement panel filter in it? would this do ok?

the rover 45 one is the same as the mg zr 160, so it supplied air to 160bhp, but i hope to be running more than that after a while.

Hello Ralph,

I use a pair of K & N airfilters in my 4.6 and they are really excellent.

Do be aware though that the K & N filter will pass more air than a standard paper element filter, so your engine will run lean unless adjustments are made to the fueling to maintain the desired air/fuel ratio.

i need a cold air feed to mine so that rights out most K&N cone filters, as engines in the back and engine bay temps will be worse than a front engined car.

being efi im fairly sure it will automatically adjust to having a freer flowing air filter, as the air flow meter should adjust it.

i have been pointed to wards a landrover 300TDI air filter, as they are big and easily located.

Why not put a snorkel/feed pipe towards the air filter and use a K&N, or I think K&N Apollo filters are in their own housing so you could just pipe either end of the filter to where you want.

the K&N Apollo would do the trick, just like the BMC cda, but they look gay and are rediculusly expensive.

does anyone know what the inlet to this box is like? would it be possable to jubilie clip a hose to it??

borrowed a TDi 300 airbox today (like the one in the pic), and looks like it would fit, does anyone have any idea if it has enough flow capacity for 200bhp aprx????

I'd say that wouldnt be a problem at all, if your still dubious you could retain the box but put bigger ports on it and make them a bit more central to the filter inside it- and put a cone filter in (or double cone) as you get much more surface area than a standard flat filter- though with a K&N I'm sure a flat replacement filter would easily handle 200bhp!!!
