On the 3rd gen Tacoma, the engine air filter is one of the easiest jobs on the truck. The airbox lives on the driver's side, the lid is held down by spring clips, and the flat panel filter lifts straight out. Most people can do it in ten minutes with nothing but their hands and a flashlight; a small flat screwdriver just makes stiff clips easier.
The mistake people make is skipping the vacuum step. The lower housing collects leaves, pine needles and dust through the inlet snorkel, and if you drop a clean filter on top of that mess you just seal the dirt in downstream of nothing. The second mistake is closing the lid on a filter that is not seated flat — you get a whistle at idle and dirt bypassing the filter edge. Check that every clip clicks and the seam has no gap.

Tool needs are the same for the 2.7L 2TR-FE and the 3.5L 2GR-FKS — both use a clip-retained lid and the same style flat panel filter. The only difference between trucks is the intake tube clamp, which may be a #2 Phillips worm-gear screw or an 8 mm hex-head worm-gear screw, and some builds have a 10 mm bolt securing the housing bracket that you normally do not need to touch.

The 3rd gen Tacoma airbox is clip-retained on both the 2.7L and 3.5L, so no sockets are strictly needed; double-check whether your truck's intake tube clamp is a Phillips worm-gear or 8 mm hex head, and confirm the filter part number against your year and VIN before buying.
Usually no. The lid is held by spring clips you can release by hand. A small flat-blade screwdriver helps with stiff clips, and a #2 Phillips or 8 mm socket is handy if you need to loosen the intake tube clamp for lid clearance.
The Toyota OEM panel filter 17801-0C010 covers both the 2.7L and 3.5L in this generation, with equivalents from Denso, Fram, K&N and others. Always verify the part number against your year and VIN at the counter, and compare the new filter to the old one before installing.
Toyota's guidance is around every 30,000 miles under normal driving. If you drive dirt roads, dusty job sites or tow in traffic, inspect it every oil change and replace when the pleats are gray and packed with debris.
The filter sits flat in the lower housing with the rubber or foam sealing lip facing up toward the lid, and the pleats running across the box. Photograph the old one before removing it if you are unsure — it only sits properly one way.
