No DIY that we have here unfortunately, but I'm sure there may be one out there somewhere on the forums. I don't think it's that difficult though, because it's pretty easily accessed right up under the hood towards the windshield/cowl area.
And all this time, I thought it would be inside the cabin somewhere, lol.
I'm going to order a set within the next 500 miles as I have 19,500 miles now. And it won't be until 30k until I get a freebie oil change.
