The dipstick that comes with the Kraftwerks supercharger is vented, so without drilling and tapping your expensive oil reservoir, you can not go through water deeper than the dipstick. With the RCOR vented dipstick, you can run the vent line anywhere you like without having to modify your oil reservoir. The RCOR vented dipstick is billet aluminum and made 100% in the USA with USA material. Each kit includes a vented dipstick, 5 foot high temp silicone hose, hose clamp and zip ties.
