Specifications
Part Details:
Fits the 2.4L FA24F engine in the 2022 and newer WRX only, not the earlier 2.0L FA20DIT WRX. Confirm your engine year before ordering.
Tuners have long relied on a colder heat range and tighter gap spark plug to keep a modified engine running clean under higher boost, and this COBB spark plug set takes the guesswork out of that upgrade path for the newest generation WRX. Running one step cooler than the factory plug with a tighter gap, it’s built specifically to handle the added heat and cylinder pressure that come with a tune, while remaining a completely reasonable choice for a stock engine too.
Trivalent metal plating provides strong anti-corrosion and anti-seizing properties, making removal easier down the road at the next service interval. Sold as a complete set of 4.

Frequently Asked Questions
Does this fit the older WRX?
No, this set fits the 2.4L FA24F engine in the 2022 and newer WRX only. The 2015-2021 WRX uses the 2.0L FA20DIT and requires a different COBB spark plug set.
Do I need this if my car is still stock?
No, this plug works fine on a stock engine too, but it’s a common upgrade to pair with a tune since the colder heat range and tighter gap are built to handle the added heat from increased boost.
How many plugs are included?
This listing includes a complete set of 4 spark plugs, enough for the full engine.
