Dirt racing filter review
We have had the best results using the spyder 4 x 14 filter. Most all of the guys we raced with have gone to use these and nobody ever complains about dust anymore. How often should we wash or is it better not to? thanks Terry Review by Terry / (Posted on 9/4/2024)

“My carburetor has never been so clean after a long night at the dirt track. Performance is amazing, clean up is simple and I am not filling my garbage with the old paper throw away filters” Review by Greg W - Portland OR / (Posted on 5/20/2024)
Best filters
I have used Spyder filters for the past 2 years and have had awesome success with them. Every time I have used other filters I see dust/dirt has made it thru. Spyder filters are by far the best on the market and not to mention good customer service. Highly recommend their product. Ray Bollinger #77 UM Review by Ray Bollinger / (Posted on 3/31/2024)
Primo filters!
We tried them all and we're never satisfied because the dust would always get past somehow.

Since we switched from the larger size filter, we have never seen a speck and the filter can be cleaned quick.

This is a outstanding race filter. Thanks Review by Laps a plenty / (Posted on 3/31/2024)
Spyder dirt filter
I have no idea how it works but this filter always keeps our stuff super clean. We go out on really dusty tracks and after racing we inspect. No dirt at all. The guys using other filters always have junk collected around the top of the carb. Thanks. Review by Bill K / (Posted on 12/17/2022)
2nd year on our filter
The filter worked great over the course of last year. We have it ready to go again for this year. Review by GaryA / (Posted on 4/14/2022)
Great dirt car filter
Always zero dirt on the carburetor and the air cleaner bottom. These work extremely well. Get one. Review by Pete H / (Posted on 6/3/2020)
Dirt Car Filter
Always incredibly clean and the car runs great. Saves us a ton of money and taking care of the filter is fast and simple. Review by Randy33 / (Posted on 5/5/2020)
Easy and fast
We ran our Spyder filter on or dirt mod all last year. Real easy to maintain and we only needed to wash it once. Just blow out the dirt and it's works great! Engine is always clean. Review by SteveB74 / (Posted on 4/10/2020)
Finally
Now we can finally stop hearing from our carb guy about how our air bleeds were always dirty.

He's happy! Good filters. Review by StuGots / (Posted on 4/5/2020)
