FIRST OF ALL WHEN TWO DIFFERENT METALS LIKE THE DIFFERENT METALS IN THE SPARK PLUG AND ALUM/POTMETAL HEAD. OF THE ENGINE HEAT UP THE EXPAND AT DIFFERENT RATES AND CAN CAUSE THE PLUG TO BECOME IMPACTED IN THE HEAD AND MAKES IT HARD TO GET OUT WITHOUT STRIPPING THREADS ESPECIALLY IN ALUMINUM. ANTI SEIZE CAN BE PURCHASED AT YOUR LOCAL PARTS STORE . SOMETIMES ITS CALLED COPPER ANTISEIZE AND IT HELPS PREVENT METALS FROM BONDING TOGETHER INTHE CASE THAT YOU EVER WANT TO REMOVE IT IN THE FUTURE.
