"We do not offer a filter for that engine. The Hp-2004 may physically fit. The internal components are not the same. Like the pressure the oil pressure relief valve is set for. The type of anti-drain back valve. The other thing to keep in mind is if you have internal engine failure the dealer will not warranty it if you are using a filter not designed and approved for that engine. The choice is yours."

I hope this answers everyone's questions. I certainly will not use this filter in the future if it hasn't been tested for compatibility with our engines. Like the man said "the choice is yours".
well I have been using this filter for OVER 30,000 miles and my engine is still running like the day I bought it. so I will continue using it but thanks for the info...
BTW it is funny that the K&N book shows the contour and this filter listed as working for it.
