pgiro 36 #1 Posted October 21, 2018 Hello, What do you recommend for a spark plug for 1977 D160 with the Onan engine? I pulled NGK B6L plugs from it but I have no idea if those are correct. Tried searching here but didn't see any good info about this. Thanks in advance. Share this post Link to post Share on other sites
