BMW 335i M Sport - 2011 (N55) - Manual - 473 BHP - Extensive Maintenance I'm selling my 2011 BMW 335i M Sport (N55), 6-speed manual, with great spec and built with a strong focus on reliable usable power. The car has been very well maintained, with roughly over 10000 spent on maintenance and sensible modifications, all done with longevity in mind. I'm only selling due to moving abroad, otherwise I'd be keeping it Modifications Built for strong, reliable power - dyno'd at 473 BHP. Pure Turbos hybrid turbo Full bolt-ons: Upgraded intercooler Upgraded charge pipe 200-cell sports downpipe Cold air intake Upgraded diverter valve Turbosmart wastegate Tuned on 99 RON fuel Car should always be run on 99 RON (V-Power, Tesco Momentum, etc.) The car has a 200 cell catted downpipe and with an x-pipe and a back box delete, it sounds fantastic. Recent Maintenance (Last 12 Months) No expense spared - all common N55 issues addressed. New electric water pump New coolant lines New valve cover (PCV) New high pressure fuel pump (HPFP) New serpentine belt The car has been properly looked after. Future Maintenance (Transparency) The only things that may be due in the future: Coil packs Spark plugs Routine oil change That's it - everything else has already been taken care of. Specification Great factory spec including: M Sport package Front & rear parking sensors Electrically adjustable seats Heated seats Cruise control Folding mirrors Dual-zone climate control 6-speed manual gearbox (rare on 335i) This is an extremely enjoyable car to drive. If I were keeping it, the next steps would be: Limited-slip differential Water-meth injection Which would safely push it over 500 BHP
