The IAG Racing Timing Belt Kit is designed as a replacement for the OEM Subaru EJ20 and EJ25 engines. Included in the kit are high quality OEM idler pulleys, IAG's high strength red racing timing belt, billet timing belt guide, and an OEM timing belt tensioner.
The included components are designed for long life and high performance. These kits function as an exact replacement for the OEM timing belt found on the 2002-2014 Subaru WRX, 2004-2021 Subaru STI, 2005-2012 Legacy GT, and 2004-2013 Forester XT.
The IAG Performance Black Racing Timing Belt is designed to work with all Subaru EJ series engines. The high-strength Kevlar construction and attractive black color make it a great choice for your Subaru engine bay. We have performed extensive testing of this belt on our Spintron testing machine, as well as our fleet of racing vehicles. In testing, we found that these belts ensure accurate timing and unmatched performance.
IAG Black Racing belts are lightweight and utilize EPDM Rubber for increased durability and performance in all climates. The Kevlar construction is 300% stronger than the OEM Subaru timing belt, and is also three times more heat resistant. The belt teeth are made of H-NBR grade rubber for additional strength.
One of the most important components in the Subaru timing system is the timing belt tensioner. Aftermarket units are known to fail prematurely, which can cause catastrophic failure. The IAG Timing Belt Kit includes an OEM original equipment tensioner assembly direct from Fuji Heavy Industries (Subaru's parent company.)
The idler pulleys included in the kit are also OEM quality units. On Subarus it is more common to experience a timing idler bearing failure than it is to experience a failure of the timing belt iteself. You can rest assured that these high quality components will provide a long, trouble-free life.
The IAG Performance billet timing belt guide is the best method to prevent your EJ engine from skipping a beat. Engineered and manufactured in our facility in Westminster, MD, each guide is machined from a single piece of 6061 billet aluminum and then anodized black for a protective finish. The guide is a strong, rigid replacement for the OEM piece and is also adjustable to set the proper clearance for the timing belt. This adjustability is especially useful when switching to an aftermarket timing belt where belt thickness may vary. The edges of the guide feature a soft corner that prevents wear on the flat side of the belt.
Note: Subaru FHI Timing Belt Small Idler pulley bolt required for 2002-2003 WRX Fitment
I used this kit on my wife's 2009 Forester XT. It came with the IAG timing belt guide for manual transmissions, I will use that on my bugeye at the next timing belt change (not applicable to auto transmissions on the Forester). Overall, the kit is great, the quality is excellent, NTN/ Koyo bearings, which are really high quality. I am sure I could have saved some money by purchasing the ASIN kit but I figured why not get the best of the best. This car has a stage 1+ OTS tune from Cobb so adding a few higher quality components isn't overkill. This is not my first Subie timing belt job but anyone can do it if they take their time. I recommend getting the company 23 cam lock tool for the driver side cams, it helps a lot with keeping those cams chillin in place while you put the belt on and its really affordable.
Hello Lando,
Thank you for your review and detailed write-up! The IAG red timing belt kit with high-quality NTN/Koyo bearings is top-tier insurance for the EJ engine, and using the Company23 cam lock tool is definitely the ultimate pro tip for keeping those driver-side cams locked in place during the install! 🛠️

It’s a great kit! But come on iag you guys should know better about packaging the belt tensioner like this because now it definitely needs bleed! Other than that would buy again!

The red looks great
Quality look and feel to the product. Just take your time when priming the belt tensioner . The roller and 2x pulleys also felt of good quality. Hoping it will keep my car running smooth for more miles.
