Is it worth spending £65 on?
Checked my air filter and is a bit grotty so been looking at replacements. Not Galway but Balmoral green actually

I've used them and plan on one for the RR. I can get one for about $50 US. Lifetime filter so for someone like me that keeps cars until finding parts becomes a scavenger hunt it's worth it. Lots of debate on how well it filters though. Some of my vehicles showed a benefit in gas mileage and other none that I could tell.

Depending on which model you need (I have LPG so needed a smaller one after having had the air box removed for the LPG fitment) you should look at Amazon. I paid about £7 for mine and it has made a huge difference to the running. Now much smoother.

I bought a Pipercross one, cheaper than K&N but better/worse I don't know. Both are washable though so it may seem dear to buy but the cost is soon recovered over the years in both mpg and Normal filter purchases. Many thanks

piper cross are cheaper than the K and N because they use a foam core, which is cheaper to make. That said I have had a piper cross in the mrs car for years now and it has been faultless.

Just looked and the do a K and N for the 4.4 TDV8 decisions........ There is nothing that can't be fixed with a hammer😜😜

If I could find one for £7 it would be a no brainer. Not a cheapskate, just having spent £4,000 in last 2 years on my ff I'm trying to save a little when I can.

From the K&Ns I've used in the past they haven't had improved surface area over an OEM item - therefore they must have larger "pores" to increase the flow. They'll let more air through but more dirt as well.

Also, if all it takes to get more power / cleaner running / more responsiveness out of an engine is to replace the air filter I suspect some manufacturers might have done it already.

My humble opinion is to use a good replacement (Mahle for example) and replace every 5 or 6 k miles (I change my oil & filter every 5k so do it at the same time).

Having said all that - a cone filter can give a very nice induction roar!!!

If you're not bored of reading this yet a quick anti-dote for you. When we were Autograssing I accidentally had a poor fitting air filter and it was a dusty day. In approx' 1 mile (4 x 400m laps) I completely detroyed an engine. Crank, pistons, block, cam,,,,, you name it - there was nothing salvagable. The YB crank which was on std before hand fair made me cry - it was a polished and balanced work of art  Back in a Defender!!

I'm with Ric, they were good 20+ years ago but they are a waste of money these days, an original or OEM will ensure more than enough clean air to the engine....

If you do decide to get one, blow it through with an airline, they come with far too much oil on them and if it gets in the MAF it will knacker it...  Pete

Thanks for advice.
Don't need any more "roar" as have Overfinch exhaust and remap, can sound a bit lairy lol
Will stick with original and with what I will save will treat the car to a new pollen filter and maybe fuel filter too. Not Galway but Balmoral green actually

K&N has a brand called AEM which makes oil-free filters that won't kill your MAF.

I'd stick with OEM if I could. I only use one because the std one doesn't fit after the facelift. 2004 L322 V8

Are you including the air filter oil needed and the time spent cleaning the filter in your economics.
