It is too cold for me to even try in an unheated garage.
Not true Russell, Aftermarket bosch don't last as long as oe bmw bosch but i've had very good results with aftermarket nippondenso/ntk/denso and they seem to last as long or longer than oe. The aftermarket bosch that everybody gets from autozone/checker/kragen and basically every small import shop are the ones i see the shorter life with.
