Your 2010 WRX is running the EJ257 2.5L turbo boxer — a rewarding engine that demands respect. At 15+ years old, the timing belt service is the first conversation you need to have with this car before anything else. Advanced skill level means I'm giving you the full picture: safety, capability, and every Subaru-specific tool you'll need to do this job right from oil changes through timing belt service and boost diagnostics.
Timing belt driven at 105k/7.5-year intervals — almost certainly overdue on a 15-year-old car. Oil filter sits in an awkward low position; use a cap wrench only. Aging boost hoses and turbo inlet boots are the number one cause of mystery power loss on high-mileage WRXs.

3.5" min height handles stock WRX easily. Aluminum build cuts weight in half vs. steel — you'll actually use it instead of fighting it out of a corner.
Alternative: Pittsburgh 3-ton steel, Harbor Freight (~$90)

6-ton stands have a significantly wider base than 3-ton — much harder to tip. Pin-style lock is more positive than ratchet pawl. Never go under a car without these.
Brand: Maxxhaul | Category: Safety | Store: Amazon | Priority: CRITICAL
Chock both front and rear before any jack goes under the car. AWD systems don't substitute for physics — gravity always wins.
Brand: Uvex | Category: Safety | Store: Amazon | Priority: CRITICAL
Keep one on the bench, one in the car, one spare. If they're everywhere, you'll actually wear them.
Brand: Kidde | Category: Safety | Store: Home Depot | Priority: CRITICAL
A 15-year-old turbocharged car with aging fuel lines and rubber boost hoses is not the place to skip this. Mount it on the wall within arm's reach of where you work.
Brand: Tekton | Category: Sockets | Store: Amazon | Priority: HIGH

WRX axle nuts are torqued to 140+ ft-lbs from the factory. Your ratchet will not touch them. Breaker bar handles this without burning through impact batteries.
Brand: Tekton | Category: Hand Tools | Store: Amazon | Priority: HIGH
Lug nuts at 89 ft-lbs, axle nuts at 140+ ft-lbs, cam pulleys — all need a torque wrench. The 24335 is accurate to ±4% without costing Snap-on money.

Brand: GearWrench | Category: Wrenches | Store: Amazon | Priority: HIGH

The EJ257 boxer engine bay is deep and awkward. You will reach for a 6" extension on every single job. Buy these before you need them — you'll need them immediately.
Brand: Tekton | Category: Hand Tools | Store: Amazon | Priority: MEDIUM
Spark plugs, valve cover bolts, and intake manifold fasteners all require low-range torque you simply can't feel through a 1/2" wrench. Non-negotiable for proper EJ head work.
Brand: Husky | Category: Lighting | Store: Home Depot | Priority: MEDIUM
The boxer engine tucked under a low hood is genuinely dark. A pivoting magnetic-base LED that charges via USB-C is the difference between guessing and seeing what you're doing.
Brand: Klein Tools | Category: Diagnostic | Store: Amazon | Priority: MEDIUM
WRX boost solenoids, MAF sensors, TGVS motors, and O2 sensors all need voltage and resistance testing. The MM400 is a real meter at a non-professional price point.
Alternative: Fluke 107, Amazon (~$65)

EJ257 timing belt service requires precise cam sprocket alignment — you cannot eyeball this. Locks the cams at TDC so the belt can be swapped without losing timing.
Brand: Mishimoto | Category: Subaru Specialty | Store: Amazon | Priority: MEDIUM

EJ257 plugs are deeply recessed in the head. Thin-wall magnetic design clears the casting and holds the plug on extraction — standard sockets often won't fit cleanly.
Brand: Lisle | Category: Subaru Specialty | Store: Amazon | Priority: MEDIUM
EJ257 cooling system has notorious air pockets — refilling without a spill-free funnel means air locks and overheating on startup. This tool fills and bleeds the system correctly every time.
