BMW M4 // SMSTuned

The M4, and its four-door sibling the M3, has a lot to live up to. The previous M3s, regardless of door count, are among the most engaging and most beloved performance cars ever built. BMW had to get this one right, and it sounds like they did.

Our client David let us rip into the essense of his M4 to create an even clearer vision of what an M car should be.  



VRSF – VR Speed Factory Downpipes / Intake / top mount Intercooler

Downpipes- VRSF is simply awesome. they  are one of the only downpipes to feature a cast stainless steel v-band to pipe transition. These 3″ downpipes are the best bang for the buck mod available for your S55, with gains from 25hp & 30tq when tuned.

Intake –

he VRSF front facing intake upgrade for your M3/M4 replaces your restrictive OEM intake with a high flow design that places the filters directly behind the front grill. Placing the filters behind the grills increases induction sound and prevents heat soak from the radiant heat in the engine bay. These intakes are constructed from mandrel bent 3″ aluminum tubing and include CNC billet aluminum MAF and vacuum flanges.
