Air Filter

[MLW]

Just replaced my Denso air filter with a new one. As it is only 10,000 miles old I was planning to hoover it clean and replace it, but it was pretty dirty so replaced it. I normally do this and replace them at 20,000 miles. What is the official service time as the state of it surprised me?

for me your piccy seems to obliterate most of your text sadly

I found in olden times an air filter would last 2 years motoring, about 20/25k miles

These past few years the air quality has gotten so bad that it NEEDS changing each and every year

Sorry, Just saw the picture. I was saying I planned to hoover out the 9 month 10,000 miles on the old filter, but it was very bad, I replaced it. 

I have checked the service book and Lexus say every 4 years or 30,000 miles which ever comes first. Heaven knows what it would look like then. Toyota said my old Prius was every 40,000 miles. I agree the air seems poorer and maybe ever 10,000 miles is becoming the new norm. Also, a big V8 must suck in much more air than a 1.6 liter engine, so one Lexus size fits all seems crazy.,
