FAQs
Will this fit my BMW 3 Series E90?
Yes, if your car is a 2005–2012 E90 Saloon or E91 Touring with M Sport trim and twin-exit exhaust. Standard models without M Sport are not compatible.
Is professional fitting necessary?
Whilst experienced DIY installers can manage bolt-on fitment, professional fitting is recommended to ensure correct fitment and finish. We offer this service in Southend-on-Sea.
What colour options are available?
This diffuser comes in gloss black. Contact Project Styling if you wish to discuss other finishes.
How do I care for the gloss black finish?
Regular washing and occasional waxing will maintain the gloss. Avoid harsh chemicals and abrasive cloths to preserve the finish long-term.
