Turbocharger Pair for BMW 335i 335is 335xi (2007-2013) 3.0L Left & Right

Direct-Fit Replacement Twin Turbochargers for 2007-2013 BMW 3 Series (E90/E92/E93)

What it Does: The direct-replacement TD03 turbocharger pair restores manifold pressure, throttle response, and lost factory boost on the 2007-2013 BMW 3 Series equipped with the twin-turbo 3.0L engine.

The Stock BMW 3 Series Wastegate & Bearing Weakness

Factory E90/E92 turbochargers are notorious for premature wastegate flapper arm bushing wear. As heat cycles accumulate, bushing play causes the wastegate flappers to misalign, creating the notorious wastegate rattle and persistent 30FF low-boost fault codes. Concurrently, high exhaust gas temperatures break down the OEM journal bearings and carbon seals, resulting in oil blow-by through the downpipes and smoke under deceleration.

The Engineering Solution

Built to factory TD03L4 specifications, this pair features reinforced internal wastegate pivot arms and precision-seated flapper valves to eliminate exhaust bypass rattle. The rotating assemblies undergo high-speed VSR balancing to stabilize the compressor wheels and turbine shafts across peak spool velocities. Castings maintain standard oil feed, coolant jacket, and downpipe flange tolerances, facilitating direct OE-style installation without custom oil line fabrication or manifold modifications.

Frequently Asked Questions & Fitment Warnings

Does this fit the E90/E92 3 Series?

Yes, this is a direct fit for the 2007-2013 BMW 3 Series equipped with the N54 3.0L twin-turbo engine. Does not fit 2011-2013 335i/335xi models equipped with the single-turbo N55 engine or naturally aspirated N52 vehicles.

What maintenance must be performed during turbo replacement?

To avoid premature thrust bearing failure, clean or replace all oil feed and return lines, pre-lube the center cartridge bearing housing, and perform a complete engine oil and filter service prior to startup.

The BMW Precision Standard

Manufactured to strict European tolerances, these matched turbochargers communicate seamlessly with standard DME vacuum control solenoids to deliver smooth power delivery without check engine lights or driveability faults.
