Looking at the sun.( air filter test)

[Chris142]

I installed this fram air filter on 9-14-19. Roughly 8 months later it is this plugged! I do not know the exact milage but around 7k. The sun was directly behind the filter. Unable to pass light.

Seems like a meaningless test without comparison to a new filter.

 

[motts]

+1

Seems more like a matter of media type and pleat density. Then again, if I took a filter out with 7K on it, I'd go ahead and put a new one in.

Can you ever see the horizon in such a dusty area?

If you look at the 8th full pleat from the right, you see an area, that appears to have 4 pin holes in it. Is that a damaged filter? the sunlight test is for K&N cotton gauze filters, showing how well it can let dirt through

Looks like something went through it.

Did the car run different before and after changing it. I've seen filters look really bad but negligible performance or gas mileage difference. Next time put a K&N in there. The never plug and last for years. most likely longer than your engine will :P

Don't use K and N until you do some research.

I have not driven it tonight but last time it made a huge difference

If it's really dirty only after 7k miles, isn't that good? Means collecting lots of dirt.

 

[bbhero]

Well you do live on the area where Thunderdome was filmed Seriously in your area and others like it in the southwest US... Far, far, far more dust in the air there versus the Eastern US.

Djd you drive thru the Saharan dust storm?

Ya but replacing a filter 2x a year

Sunlight test is useless and non-scientific. K&N allow sunlight through because the oil is transparent enough to allow it to happen.

AEM makes a much better reusable air filter than K&N

Now we know why the grub hub delivery girl walked the last mile to your house. Trying to keep her air filter clean!

Might be time to tie some old pantyhose or cheesecloth over your air inlet opening? That actually looks black, like you've been following a chipped "brodozer" diesel pickup around!
