- Unless advanced at clutch tuning we do not suggest running any springs without our clutch kit
- Measured at 2.45" & 1.25"
- Green/Silver 75-175 Spring: This is the lowest engagement spring we offer but also has a lower spring rate up top than our standard clutch kit springs, so you will lose 100-200 RPM and weights will need to be 1-2 magnets lighter to achieve the same peak RPM.
- Gray/Red 80-200 Spring: Excellent spring that is sometimes used in our clutch kits. Nice engagement around 1700-2000 RPM while still keeping the final spring rate (full shift rate) up close to our standard gray/yellow spring.
- Gray/Yellow 85-240 Spring: This is our standard clutch spring found in our P90X HD clutch kits with an engagement of 1800-2100 in most cases.
- Gray/White 115-240 Spring: Race Spring. This spring has the same full shift rate found in our gray/yellow standard primary spring, but has an engagement of 2500-2700 RPM. Keep in mind this spring will be harder on your already weak clutch because of the harsh engagement. Great to use with launch control if you want to risk it.
- Gray/Black 105-275 Spring: This is a great spring that engages at 2200-2300 RPM in most cases. This spring has a higher full shift rate which raises peak RPM around 200-300 RPM. Some may find this is a good dune spring if switching back/forth from dune to trail setups... you can install this spring when heading to the sand. This spring normally makes up most the RPM lost from the extra sand load, so adjusting weights may not be necessary.

Great filter and easy installation
Style: BE-159 1-Pack, Style: BE-159 1-Pack
For my 2016 Hyundai Sonata Hybrid Limited. I cannot believe I paid so much more for a brand-name filter that does the same thing as this one. It is made of the same material as the dealer one I took out. Very easy to install, cant believe I paid for this to be done in the past with oil changes. Requires no tools and did not get dirty at all. No mechanical skills needed, especially if you run into trouble and can use YouTube.
PROS
- great quality, cannot tell that it is after-market
- very professionally made, not irregularities seen
- excellent fit in position, no adjustment needed
- very easy to install, cannot believe I paid to have this done in the past
- no mechanical skills needed to install
- great price compared to what big name productions want for the same thing
- cannot tell the difference in air quality between this and the dealer filter I took out
- removes outside odor completely
- did not require tools are getting dirty
CONS
- None

Fits perfect and works as designed. Flows like OEM and looks well made.
Style: BE-553B 1-Pack
This filter is very comparable to the stock filter. Fits the BMW G20 just like OEM. I would not say it is two times "heavier" as advertised on the box, but it is very comparable to stock. It's the same weight and similar construction. BMW has a very robust cabin filter. This will be my go to. I did purchase another aftermarket cabin filter that fit well, but was thin, flimsy and had a bad chemical odor. This one is fine and airflow is the same as OEM. I change them every year or so. I don't worry too much about longevity with cabin filters personally.

Good quality but it was slightly longer than original and needed modification.
Style: BE-182 1-Pack
Bought this cabin filter for a 2023 Acura TLX. While the filter seems to be made of quality material, it was just a little too long (about a 1/16 of an inch, so I had to trim it to make it fit so the cover would fit snug. I was able to do that without compromising the filter itself. But this might be an issue for some people

Fits my Chevy 2021 Bolt Premier perfectly.
Style: BE-966 1-Pack
Installation was a breeze, fir nicely and the air in teh car now smells fresh and clean. The old filter has developed a musty smell so this new one is great. Had it replaced in under 3 minutes.

Fits perfectly for my 2017 VW Passat
Style: BE-373 1-Pack, Style: BE-373 1-Pack
Bought this for a fraction of the cost. An auto shop wanted to charge me $72.99 for a filter so I bought this Spearhead brand cabin filter and its the perfect size and its just as sturdy as the previous one the dealership had in the car. Not sure yet how the airflow is or if anything different as I have not driven in the car since it was replaced, but it appears to be a very high quality cabin filter for my car at a great price.
