Best Performance Upgrades for BMW 3 Series in Canada

The BMW 3 Series is one of the most modified sport sedans in Canada. Here's what delivers the most improvement, available at MyPartsGuy.ca priced in CAD with no duties.

Suspension — The Most Impactful Upgrade

Eibach Pro-Kit springs for the BMW 3 Series drop 25–35mm with a progressive rate that works particularly well with BMW's sophisticated multi-link rear suspension.

KW coilovers for the 3 Series are the premium choice — KW's V2 and V3 for BMW are specifically engineered for the platform. Bilstein B14 and B16 coilovers offer excellent monotube quality at a more accessible price.

Brake Pads

Hawk HP Plus front pads for track use. For street use: Hawk HPS 5.0 delivers noticeably better cold bite than OEM with low dust.

Cold Air Intake

aFe Power's Momentum and Takeda intakes for BMW deliver 8–15 hp with improved throttle response on turbocharged N54, N55, B46, B48, and B58 engines. K&N's BMW-specific intakes are the value alternative.

Exhaust

Borla's BMW applications strike the right balance — the S-Type delivers a European sports car character. MagnaFlow carries multiple 3 Series applications at a lower price point.

Cooling — N54 and N55 Specific

Mishimoto's BMW cooling products address known heat soak issues on turbocharged 3 Series builds.
