FCS II Infill Kit
- Durable silicone construction: The infills are made from high-quality silicone rubber, designed to withstand extreme temperatures and corrosive conditions without damaging plugs or fins.

- Complete kit contents: The kit includes one center compatibility infill, four side compatibility infills, ten grub screws, and one FCS key for installation.
FCS II Compatibility Infills are designed to fill the gap, literally, between the front tab of the original (dual tab) FCS fin and the front of the FCSII plug front slot. These infills are made from high quality silicone rubber which will not damage the plugs or fins (they are also extremely durable, light and built to withstand extreme temperature and corrosive conditions). Includes Centre Compatibly Infill (x1) Side Compatibility Infills (x4) Grub Screws (x10) FCS Key (x1) Reusable zip lock bag FAQ Will my old FCS (dual tab) fins work with the FCS II system? Yes, you can use all your existing FCS fins with the FCSII system; however the FCS MF-1 fin pictured is not included. The FCSII plugs are backwards compatible - grub screws can be used within the FCSII plugs to secure your existing dual tab FCS fins. FCS has designed a set of unobtrusive silicone infills to fill the gap created by the old fins in the new system. The infills are made from high quality silicone rubber which will not damage the plugs or fins. They are also extremely durable, light and built to withstand extreme temperature and corrosive conditions. The infills replicate the flush leading edge of the new fin design improving the performance of the old fins.

Perfect fit!
Size: 14-22 2.0L hybrid, Size: 14-22 2.0L hybrid
This is a good value for a combo package which includes a cabin air filter as well as the engine air filter. Both filters were a perfect fit in my 2019 Honda Accord hybrid. The cabin air filter airflow direction is clearly labeled and the pleats are sturdy. Installation was super easy- just drop the glove box cover, pop the cabin filter cover plate, pull out the grungy old filter and pop in the new one. Easy peasy. The engine air filter is also a perfect fit. No complaints or concerns here.

INFISTAR AC85111 Cabin Air Filter
Perfect fit! So grateful for you carrying this and the great price. My AC has been out for about a year but when I replaced this, it now works again! Had no idea there was such a thing.

Cabin air filter for Honda
Cabin air filter was an exact fit and arrived the next day. Seems to be of comparable quality to OEM part and was significantly cheaper.
