If you're looking to boost the low to mid-range power of your street car, tow vehicle or jet boat with a near stock Toyota 1UZ-FE engine, consider upgrading with performance cams. These cams can be easily installed on OEM valve springs and maintain drivability while delivering significant improvements. 

• For high mileage engines, Kelford Cams recommends KVS1UZ valve spring, which can help enhance the performance of your engine.
