Fiat 124 Spider Parts & Accessories

Fiat 124 Spider Parts & Accessories

The Fiat 124 Spider produced from 2016 to 2020 combines a Pininfarina-inspired open-top body with Mazda MX-5 underpinnings and a Fiat-developed 1.4-liter MultiAir turbocharged inline-four engine producing 160 horsepower, creating a distinctive Italian-flavored roadster with the mechanical reliability and parts availability of a high-volume Japanese platform. The MultiAir engine's variable intake valve timing system and turbocharger deliver a broad torque curve that suits both spirited backroad driving and highway touring, while the shared Mazda chassis provides precise handling and a direct steering rack feel that rewards driver input. Owners who appreciate both Italian character and Japanese engineering precision find the 124 Spider a compelling platform for both OEM-quality service parts and performance upgrades. This collection covers the complete range of parts and accessories specific to the Fiat 124 Spider's unique powertrain and Mazda-derived chassis.

Popular Upgrades

Aftermarket exhaust systems from Borla and Invidia designed for the 124 Spider's 1.4T engine provide improved exhaust flow and a more characterful soundtrack compared to the factory muffler, with cat-back and axle-back configurations available to suit different noise level preferences. Turbocharged intake upgrades including high-flow air filter housings and short-ram cold air intakes from AEM and Injen improve throttle response and top-end power delivery on the MultiAir engine. Coilover suspension kits from BC Racing and KW that leverage the MX-5's well-established aftermarket fitment data, and upgraded brake pads from EBC and Hawk Performance, round out the most popular upgrade paths on this platform.

Performance and Handling

The 124 Spider's MX-5 platform provides a near-ideal 50:50 weight distribution and a front MacPherson strut and rear multi-link independent suspension that responds exceptionally well to lowering springs and upgraded sway bars. The Mazda-derived chassis has extensive aftermarket support developed for the MX-5, meaning many suspension, brake, and wheel components are interchangeable between the two models with correct fitment verification. The 1.4T MultiAir engine's turbocharger is positioned low in the engine bay with a relatively short intercooler path, making upgraded intercooler piping and heat-shielded charge pipe kits effective in reducing heat soak under sustained high-load driving.

What makes the Fiat 124 Spider different from the Mazda MX-5?

The Fiat 124 Spider uses a distinct body shell, interior design, and front fascia compared to the Mazda MX-5 despite sharing the platform, meaning all body panels, interior trim pieces, and front suspension geometry components specific to the 124 Spider's longer nose and different hood structure are unique to the Fiat. The MultiAir turbocharged 1.4-liter engine is entirely different from the MX-5's naturally aspirated 2.0-liter Skyactiv unit, making engine service parts, exhaust manifolds, turbocharger components, and air intake systems completely non-interchangeable between the two cars. Wheel fitment, brake caliper positions, and some suspension pickup points are shared, so wheels, rotors, and strut components from the MX-5 fitment catalog often cross-reference correctly to the 124 Spider.

How do I maintain the 1.4T MultiAir engine in the Fiat 124 Spider?

The MultiAir engine requires the use of Fiat-specified 5W-40 full synthetic oil rated to the ACEA A3/B4 specification, as the variable valve timing system's hydraulic actuation is sensitive to oil pressure and viscosity outside of specification. Spark plug replacement at the factory-specified interval using NGK or Champion iridium plugs in the correct heat range prevents misfires that can damage the catalytic converter under partial load conditions. The turbocharger's oil feed line and wastegate actuator should be inspected at each major service, and using a quality catch can between the PCV valve and the intake manifold reduces carbon buildup on the intake valves from recirculated crankcase vapors.

Why These Parts Fit Right

Every part in this collection is cataloged to the 2016 to 2020 Fiat 124 Spider's MultiAir 1.4T engine and MX-5-derived chassis specification, clearly distinguished from the classic 1966-1974 Fiat 124 Sport Spider that uses completely different mechanical components. Compatibility data covers both the standard and Abarth high-performance variants with correct engine tune and suspension specification differences. Fast shipping from stocked inventory keeps your 124 Spider's service and upgrade plans on track.
