Michael, your call entirely, but the K&N oil filter also has the hex nut welded to the top for easy removal. On this forum alone, 4 or 5 cases of the weld failing and the filter leaking have been reported. Luckily, no one has been hurt. I witnessed one of the incidents and it resulted in oil all over the engine and exhaust. While my suspicion is that K&N got one dodgy batch, I will never use another one; nor will I use any other filter with an extraneous nut welded to it—for example, the HiFlo racing filter.
