This how to may apply to Tacoma's and FJ Cruisers with the exact same 4.0L engine. Please consult your owner's manual before trying.
It is probably impossible to damage the Mass Air Flow sensor and wiring but be careful not to rip off the top portion with all your might. Just open it enough to remove the old filter.
I am going to try the Genuine Toyota Parts TRD Air Filter next interval to see if there is any difference in power and MPG. A reusable performance filter may be more cost effective in the long-run, especially in dusty climates. Also, the standalone TRD air filter is a cheap alternative to the Genuine Toyota TRD Cold Air Intake System and it does not require any installation.
I heard of dealerships charging 1/2 an hour of labor to change the engine air filter. Save yourself time and money by doing it yourself.
The owner's manual says to change every 30,000 miles. Personally, I would not go more than 15,000 miles.
I use Meguiar's Natural Shine Protectant to dress the plastic in my engine bay. I really like the natural, low-gloss shine and how long it lasts.
