Where can I buy a booster plate?TA doesn't make a booster plate.Your question should be "What is the difference between the Ruggles/Kenne-Bell booster plate and the Melling pump cover surface restoration plate.The booster plate creates a flat surface that does away with the open cavity in the stock pump cover. This creates better pump efficiency,especially at lower rpm. Since bypassed oil is returned to the pump gears through the open cavity and the cavity is no longer there with the booster plate,a channel to reroute the bypass oil back into the oil intake stream is machined into the stock cover with a Dremel rotary tool. The Melling plate is used to provide a new unscarred surface for the pump gears to ride against. The plate retains the open cavity for bypass oil to return to the pump gears,therefore it doesn't do anything to increase efficiency.
Ta advertises it on their website as a booster plate that's why I said that. They're the ones that need to correct their website then.
