🔧 Repair Overview

Air Filter Replacement is one of the most common repairs for 2012 Lexus IS. This repair involves replacing the damaged engine component with a new or refurbished part. The process typically takes 15-20 min and requires easy skill level.

🔧 Required Tools

What You'll Need

  • Replacement engine part (OEM or aftermarket)
  • Precision screwdriver set (Phillips #000 or pentalobe)
  • Opening tools (plastic spudger, suction cup)
  • Adhesive strips or glue
  • Clean workspace with good lighting

Step-by-Step Process

Step 1: Lift the car

Step 1 - Image 1
Step 1 - Image 2

I used home-made wooden car-ramps, but you can use a jack and jack-stands, or store-bought ramps

Step 2: Gather your tools

Step 2 - Image 1
Step 2 - Image 2

The tools I used were:

14mm wrench for drain bolt

Toyota filter housing wrench

1/2in rachet to drive the filter housing wrench

Drain pan and clean/dirty rags

Pick or small screwdriver to pull off the old O-ring

Philips 3 screwdriver to remove filter housing access panel, can also use 10mm socket

Big-mouth funnel

Step 3: Remove oil filter housing access panel

Step 3 - Image 1
Step 3 - Image 2

Remove the filter housing access panel with the screwdriver or 10mm socket

There are 3 screws

Step 4: Drain the oil

Step 4 - Image 1

Position your drain pan under the oil pan - it's right-side of engine

Remove the oil pan drain bolt and try to avoid the mess!

Step 5: Re-install the drain bolt

Step 5 - Image 1
Step 5 - Image 2

Once the oil is drained, wipe around the drain hole with your rags

Re-install the drain bolt with your 14mm wrench or socket - don't over-tighten it!

You're supposed to replace the washer on the bolt every time, but sometimes you forget to buy new ones

Step 6: Remove the oil filter housing

Step 6 - Image 1

Reposition your drain pan under the oil filter housing

Loosen the filter housing with your filter-housing-tool, or possibly with large channel-lock pliers...

While loosening it will start to drip - reposition your drain pan as required

Remove the filter housing completely

Step 7: Install new filter and clean filter housing

Step 7 - Image 1
Step 7 - Image 2

Remove the old filter from the housing

Clean out the housing as required

It's usually at this point I switch to the next cleaner level of rag

Remove the housing o-ring with a small screwdriver or pick - there is actually a cut-out in the lip to allow easy access - Thanks Toyota

Wipe some oil on your new O-ring and ensure it's in the correct groove in the housing

Step 8: Re-install filter housing and cover

Step 8 - Image 1
Step 8 - Image 2

After preparing the filter housing with new filter and o-ring, screw it back into the opening

It does not need to be super-tight, it seals with the o-ring, just snug it up

Re-install the cover using your 3 screws from before, I recommend only using a screwdriver, since you want to barely torque these - they go into plastic

Step 9: Re-fill the engine with oil

Step 9 - Image 1
Step 9 - Image 2

Now it's time to go up-top and re-fill the engine with Oil

I used Penrite HPR 5

My 2008 Lexus IS350 took around 6.6L of oil to fill

After I put in around 6L I took it down off the ramps to level the car before taking the final readings on the dipstick

The dipstick is on the right-side of the engine on IS350

The dipstick will only read correctly when the car is on level ground

Now you get to clean up the mess with your remaining rags or kitty litter or whatever.

Usually I start up the engine and run it for around 5 seconds (while listening intently) then check under for leaks

Step 10: Final tool detail

Maybe you have questions about the filter housing tool?

It's a Moker, I got it from Amazon [link|https://www.amazon.com/Moker-Compatible-2-0-5-7-Highlander-Accessorie/dp/B083SRNWJB/]

I'm in New Zealand, so the car is a JDM import from Japan, and I'm using locally-purchased Australian Penrite HPR 5 oil, and a Japanese JS Asakashi OE116J filter bought online from Singapore
