Gain a prominent advantage over the competition with the MFactory Helical Limited Slip Differential.

Whether used on the Street, Strip or Track, all MFactory Helical LSD's come with a Lifetime, No-Hassle, Globally Transferable Warranty

No-Load/One-Wheel Syndrome
A common misconception is that a Torsen-Style Differential is useless under a no-load situation (e.g One wheel in the air). Although true to an extent, this no-load situation does not apply to the modern day car with Traction Control (or eDiff). For those without traction control, there is a very commonly used solution to the problem (used by professional race car drivers over the past 30+ years) that our competitors will not tell you; simply left-foot brake

Save your plastic cage on the factory filter
This fit the plastic holder that comes with the factory filter. Make sure that you don’t discard the plastic “cage” that is on the factory filter. Reuse the cage with this filter.

2023 RAV4 Hybrid
The product is great and is OEM+ in quality. This has to be the easiest cabin air filter I have ever changed. The replacement is super simple. Take off the glove box by pressing in (check for Youtube videos), remove and take the plastic tray out, remove the old filter, and install the new one into the plastic tray, making note to match the direction of the arrows. Reinstall and you are done. Replace once a year.
