High flow replacement air filter kit for all R129 SL600 1992-2002.

This kit replaces the entire OEM airbox assembly from the MAF sensor forward. Our custom MAF adapter utilizes the clips and O-rings from the OEM airbox for a factory fit and airtight seal. Simply remove your airboxes and install these in their place. 30 min installation. 

The OEM SL600 air filters each have a surface area of roughly 30 in², which is exceptionally undersized for a 6.0 liter engine. Each of our filters have a surface area close to 90 in² to ensure the engine never runs out of fresh air, and the higher flowing media makes it easier for the engine to access more air at any point in the RPM range.

This results in quicker throttle response, more torque at lower RPMs, and a stronger pull all the way through redline. 

All of our intakes include high-quality American-made air filters with 99% filter efficiency. No cheap Chinese filters here, only the best for your beloved Benz. These custom air filters provide almost double the surface area over the factory filters in a more compact & efficient design. These are dry element filters. No oil to damage expensive MAF sensors. Clean, rinse, dry, and reuse every 10k miles. The reusable design means you will never need to buy another air filter ever again.

All intakes now also include our precision engineered ram-air intake ducts. By directing fresh, high-velocity air into the intake path, these ducts help create a mild “ram air” effect at speed—building higher air pressure at the filters. The result is a denser air charge, improved throttle response, and greater efficiency.

All plastic parts are constructed from premium engineering-grade materials for superior heat resistance, chemical resistance, and strength. Much stronger than the factory components.

There are differences in MAF sensors and temp sensor locations so please select your correct model year when ordering.

All air filters are custom-ordered. Please allow 2-3 weeks for product to ship.
