I've read about the issues some have had putting in the K&N on this year TC, but I'm not going to dig into this until we have at least a couple hours, or more, of dry weather here. I don't need it so bad to get soaked doing it.
As for oil changes - I find these to be the least satisfying to do myself. I do my own oil changes on my collector cars, for obvious reasons, but to move those out of the garage (when I had one to move them out of) to do contortionist moves on these new cars to reach where they put filters, and such, has not been happening of late. But I doubt I'd have an issue doing it if I wanted to. I'm not yet familiar with what's under the hood, or under the van, since the same soaking issue would apply. Spring will be here soon enough and I hope to be fully equipped with what I learn here, and elsewhere, with the things I'll do to it. Hopefully by then I'll have some forward movement on my garage... fingers crossed.
Thanks Fifty150 for your tips.
