600cc - BMW E60/E63/E64 S85

The spray pattern on these 600cc injectors is noticeably finer than the stock ones, and my S85 is running smoother through the whole rev range. About halfway through the set now, and the fuel mixture has stabilized perfectly after the swap.

The install was straightforward since these are a direct vehicle-specific replacement, and the 600cc flow rate has brought my fuel mixture back to perfect after years of hesitation.

After swapping out the old injectors, my E63 is running smoother than it has in years—these 600cc units are a direct bolt-on, and the idle is finally steady. Definitely worth the upgrade for the peace of mind.
