Fitment Notes

• Fits Subaru EJ20 2.0L and EJ25 2.5L flat-four (boxer) engine applications across the Impreza, WRX, WRX STI, Forester, Baja, Legacy, and Outback - confirm your engine code before ordering. Common compatible codes: EJ205, EJ207, EJ255, EJ257, EJ251, EJ252, EJ253.
• Not compatible with Subaru FA, FB, EJ18, EJ22, EZ30, or EZ36 series engines - confirm your specific engine family before ordering.
• All Subaru EJ-series engines are interference engines - timing belt failure results in immediate and severe internal engine damage including bent valves and potential piston contact. Replace on or before the manufacturer's recommended service interval (typically 60,000-105,000 miles depending on model and market).
• This is the Gates T328 PowerGrip Premium OE timing belt - the OE-equivalent black replacement belt. For builds requiring the RPM Racing series with 300% greater strength and 3x heat resistance, order the Gates T328RB (blue) instead.
• Always replace the tensioner pulley (T42146), hydraulic tensioner body (T43138), and all idler pulleys concurrently with the timing belt. Worn ancillary components accelerate new belt wear and can cause premature failure on an interference engine.
• Sold individually - one (1) timing belt per package.

Features

• Gates PowerGrip Premium OE - manufactured by Gates, the world's largest OEM timing belt supplier, the T328 is produced using the same high-grade materials and manufacturing processes as the original Subaru factory belt, providing OE-equivalent or better service life and performance in the EJ-series timing system without the uncertainty of unknown-origin aftermarket alternatives.
• PTFE-infused tooth jacket - the T328's tooth jacket is infused with PTFE (polytetrafluoroethylene), reducing frictional losses and tooth shear at the cam and crank sprocket engagement interfaces throughout the belt's service life, lowering heat generation at the tooth contact zone and extending both tooth jacket and sprocket service life compared to standard nylon-jacketed replacement belts.
• High-grade HNBR rubber compound - the belt body is manufactured from High Saturation Nitrile Butadiene Rubber (HNBR / HSN), providing superior resistance to heat aging, ozone degradation, oil contamination, and the water-based coolant exposure inherent in the EJ engine's timing cover environment compared to conventional neoprene or standard NBR compounds.
• Aramid-reinforced nylon tooth jacket and backside jacket - both the tooth faces and the flat back surface of the T328 are jacketed with aramid-reinforced nylon, increasing the belt's resistance to tooth wear, back-surface abrasion from idler pulley contact, and the lateral forces generated by the EJ-series multi-pulley timing drive layout across the belt's full service interval.
• Premium high-strength fiberglass tensile cord - the fiberglass cord running the length of the belt maintains dimensional stability under the tension loads of the EJ-series timing drive, resisting elongation that would cause cam timing drift and the associated idle, power, and emissions issues that develop gradually as a worn timing belt stretches beyond its design limits.
• Timing marks included - the T328 includes factory-position timing marks for accurate cam and crank timing alignment during installation, matching the original belt's mark positions for straightforward OE-spec installation without requiring additional timing tools or reference marks.
• Precision tooth profile - precision-formed Modified Curvilinear (III) profile teeth provide consistent positive engagement with the EJ-series cam and crank sprocket tooth geometry across the full 281-tooth belt, ensuring quiet, accurate timing drive operation without skip or noise throughout the service interval.
• OE exact quality rating - the T328 carries Gates' OE Exact quality designation, reflecting its manufacture to OEM dimensional and material specifications rather than to a lower-cost aftermarket tolerance, ensuring the same fit and function as the original Subaru factory belt it replaces.

Product Description

The Gates T328 is a PowerGrip Premium OE timing belt for the Subaru EJ20 2.0L and EJ25 2.5L flat-four engine family, covering the 2002-2014 Impreza and WRX, 2004-2021 WRX STI, 2004-2013 Forester, 2004-2006 Baja, 2005-2012 Legacy, 2005-2009 Outback, and 2005 Saab 9-2X. With 281 teeth, an 8mm pitch, and 88.504 in. pitch length, it replaces Subaru OE part numbers 13028AA200, 13028AA240, and 13028AA250. Manufactured by Gates - the world's largest OEM timing belt supplier - the T328 is produced using the same high-grade HNBR rubber compound, premium fiberglass tensile cord, and PTFE-infused aramid-reinforced nylon tooth jacketing used in OE timing belt production, providing OE-equivalent or better service life without the uncertainty that accompanies lower-tier aftermarket alternatives for an interference engine application.

The EJ-series engines are interference designs across all variants from the naturally aspirated EJ251 to the turbocharged EJ257 in the WRX STI - valve-to-piston clearance is zero when the belt fails and the crankshaft continues rotating. This makes the quality of the replacement timing belt a genuine safety-of-the-engine issue, not simply a maintenance preference. The T328's PTFE-infused tooth jacket reduces frictional losses and tooth shear at the sprocket engagement interface, extending both tooth life and sprocket service life compared to standard replacement belts. The aramid-reinforced nylon jacket covering both tooth faces and the belt backside addresses the multi-pulley EJ timing drive's demanding wear environment. And the premium fiberglass tensile cord maintains dimensional stability under load to prevent the gradual cam timing drift that standard belts develop as they approach end of service life.

The T328 is the standard OE-equivalent black replacement belt. For modified EJ builds - turbocharged applications running elevated boost, upgraded camshafts, or elevated redlines - the Gates T328RB RPM Racing belt (blue) provides 300% greater tensile strength and 3x the heat resistance of standard replacement belts for the additional performance margin these applications demand. Either way, always replace the cam tensioner pulley (T42146), hydraulic tensioner body (T43138), and all idler pulleys concurrently. Sold individually.
