Vehicle Fitment

• 2001-2005 Honda Civic (7th Gen / ES/EP chassis - DX, LX, EX, HX, Si EP3 - all trims, FWD)
• 2002-2006 Acura RSX (DC5 - Base, Type-S - all trims, FWD)

Fitment Notes

• Fits all 7th Generation Honda Civic (2001-2005) trims including the EP3 Civic Si hatchback - all ES and EP chassis configurations confirmed.
• Fits all Acura RSX (DC5) trims including Base and Type-S from 2002 through 2006.
• This hub is designed for aftermarket steering wheel installation only - the factory OEM airbag steering wheel cannot be reinstalled using this hub.
• For vehicles equipped with an SRS airbag system, the airbag must be properly disabled and deactivated before installation. This hub does not include airbag resistor wiring or SRS bypass functionality.
• Compatible with MOMO, Sparco, OMP, Simoni Racing, NRG, and any other aftermarket steering wheel using a 6 x 70mm PCD bolt pattern. Not directly compatible with Nardi or Personal wheels (74mm PCD) without a separate PCD adapter.
• Does not fit 1996-2000 Honda Civic (6th Gen / EK) - use MOMO hub #4920 for that application. Does not fit 1992-1995 Honda Civic (5th Gen / EG) - use MOMO hub #4911 for that application.

Features

• MOMO-patented collapsible hub design with an engineered crush zone - deforms under high-impact force in a collision to significantly increase driver safety over rigid hub alternatives.
• Splined aluminum base precisely matches the OEM 33-spline, 16mm steering column shaft of covered Honda and Acura applications for a secure, wobble-free fit.
• Pre-drilled 6-bolt mounting face accepts all aftermarket steering wheels using the standard MOMO 6 x 70mm PCD bolt pattern.
• Matte black powdercoated finish provides corrosion resistance and a clean, professional appearance inside the cockpit.
• Collapsible steel center section creates a "crush zone" tower structure - engineered in the same principle as automotive front crumple zones to absorb impact energy during a collision.
• Plastic bellows cover conceals the collapsible center section for a finished factory-quality appearance after installation.
• Exceeds German TUV safety standards - one of the most stringent aftermarket safety certification standards in the automotive industry.
• Designed and manufactured in Italy by MOMO - the originator and pioneer of the collapsible steering wheel hub concept.

Product Description

The MOMO 4929 is a vehicle-specific collapsible steering wheel hub adapter engineered for the 2001-2005 Honda Civic (7th Generation / ES/EP chassis, including the EP3 Si hatchback) and the 2002-2006 Acura RSX (DC5, Base and Type-S). It provides the critical mechanical connection between the vehicle's factory steering column and any aftermarket steering wheel using the standard MOMO 6 x 70mm PCD 6-bolt pattern - including wheels from MOMO, Sparco, OMP, NRG, and Simoni Racing. This hub is the correct fitment for both the naturally aspirated EP3 Civic Si and the K-series powered RSX Type-S, making it a go-to choice for two of the most popular early 2000s Honda/Acura sport compact platforms in the aftermarket community.

The defining characteristic that sets MOMO hub adapters apart from generic alternatives is the collapsible center section design. Aftermarket steering wheels use rigid rims that cannot deform the way OEM steering wheels are engineered to in a crash. The MOMO 4929 compensates for this with a collapsible steel tower structure that creates a controlled deformation zone - absorbing kinetic energy in a frontal impact and improving driver safety significantly over solid hub designs. This engineering meets and exceeds the stringent German TUV safety certification standard. The 33-spline, 16mm aluminum base mates directly to the factory steering column shaft for a precise, wobble-free fit with no modification required.

Installation is straightforward: mount the hub's splined base onto the factory steering column, secure the aftermarket steering wheel to the 6-bolt face, and finish with the included plastic bellows cover for a clean appearance. A compatible MOMO horn button (sold separately) is required to retain horn functionality after installation. The 4929 is widely used on EP3 Civic Si and RSX DC5 builds for track days, autocross, time attack, and street performance applications - making it one of the most trusted hub choices for this generation of Honda and Acura sport compacts.
