From the first prototype camshaft belt drive ever manufactured by Dan Jesel back in 1982 to the sleekness of today's CNC machined pieces, Jesel Camshaft Belt Drives continue to lead the industry as the premiere camshaft belt drive assembly.In the never ending quest for more horsepower, engine builders in the 1970's began using larger cam lobes which in turn required stiffer springs. The stiffer springs allowed the engine to turn more rpm, but eventually became too much for a timing chain to handle. At the time, gear drives were the only solution, but they bring with them their own set of problems. Gear drives transfer a tremendous amount of crankshaft harmonics to the valvetrain, not to mention taking incredible amounts of horsepower to drive.
As necessity is the birth of most components in high performance engines, the Jesel Camshaft Belt Drive was created to solve these problems.
Recognising the need for improvement, Dan Jesel did what he does best. Using internal cam belt assemblies as a blueprint, Dan engineered a system to externally adapt this technology to a small block Chevrolet. After sourcing a belt and gathering material, Dan went to work manufacturing the prototype pieces and in conjunction with a local engine builder successfully built and tested the drive on a NHRA Competition Eliminator engine. The results were more than impressive and the dyno numbers proved it.
To date, Jesel has engineered an arsenal of over 40 belt drive assemblies. So, whether you're on a six second pass down a quarter mile drag strip, racing in a 24 hour endurance race or just taking a trip down to the local car show, you can be assured that the components controlling your cam timing are of the highest standards and machined to exacting tolerances.

Good Fit & Fresh Air, But Slightly Reduced Airflow
I recently installed this cabin air filter in my 2024 4Runner, and it fits perfectly. It does a great job of filtering out the dusty Las Vegas air, leaving the cabin smelling fresh. However, I did notice a slight reduction in Airflow, on the highest blower setting, it feels like the output is about 25% lower than usual. It’s still early to tell how it will perform long term, but so far, it's doing its job well. If you prioritize air quality over maximum airflow, this is a solid choice at a good price too!

Filter fits well into cabin filter compartment of 2011 Toyota Avalon Limited.
Fits easily into my cabin filter slot of my 2011 Toyota Avalon Limited. It has performed well after a month of use. The design of this filter appears to be superior to the filters that are utilized at the Toyota dealer.
The filter was easy to install via the back of the glove compartment.
