This is a Greddy magnetic oil drain plug that contains a neodymium magnet - one of the most powerful permanent magnets known! Google/Wiki it for proof! These are great to use in your car due to their strength - they'll grab anything magnetic in your oil pan and not let go!
This little drain plug is holding TWO steel short shifters that weight 2.7 pounds!
Available in 3 sizes:
M12 x 1.25 = 13901301 M14 x 1.50 = 13901302 M20 x 1.50= 13901303
M14 x 1.5 is the size for the stock oil pan on a 3000GT/Stealth/GTO.
And just because SOMEONE will ask... The shifters are NOT included. But they are available here. :-)
