now i know how much FUN i am gonna have when i replace the air filter on the car...HOLY!! that's a lotta stuff to remove for some damn air filters!!!!!

Haha it's honestly not as bad as it looks. I did this for my 40k and taking the bumper off is a 20 min job at most. Right after taking that off, you take off a few screws holding the filter cover and that's it.

Thank goodness we only have to do this every 40K.

To remove the duck tail, lights and bumper it is pretty straight forward......my oil was still draining when I removed the last fastener holding the bumper on so it doesn't take that long.

Are you doing plugs too? Serpentine belt??

Wow. After looking at those pictures, I miss my honda civic.

Replacing the air filter every 40k? I thought this was replaced every oil change / 10k? No?

Engine air filters replaced every 40,000 miles or 4 years whichever first.

And the sparkplugs too and while the rear bumper cover is off I also had replaced the serpentine belt (per LexVan).

Ahh...the real benefit of the NA cars...no turbo plumbing to R&R to change the filters.

I ran out of time last night for the plugs.... 4:30 am comes up pretty quick.

Last night activities consisted of Interior/Exterior HVAC filters, Air Filters, Oil Change ...... Spark plugs are next on the agenda for tonight.

The belt was changed at 60K as part of the PDCC service and still looks great.

i was thinking about putting BMC filter in when i change it next time (i just got the car and the belt and filters were done just as the CPOed the car along with the oil change)

now that i know the bumper comes off, i am probably gonna do that WITh the PSE exhaust that i am planning to put in :-)
