My 2015 Lexus RC F is approaching the 60,000 mile service. I still have a couple thousand miles, but I decided to get ready ahead of time. I purchased the differential fluid when I did the oil change over Christmas. I have been purchasing ignition coils periodically one at a time to have them ready. Although, it seems I do not need to change them when I change the spark plugs unless the coil is bad. They are there for just in case now. Late last week, I purchased an air filter to replace the K&N filter I have. It's been in there since I purchased the car. I have "refreshed" it twice, but I feel it's time to replace it altogether. Along with the air filter I purchased spark plugs too. Odds and ends are the gaskets for the differential plugs and a new battery bar I purchased from Figs Engineering. There's a transfer pump I picked up from Amazon, but I then saw it at my local Harbor Freight for half the price. I saw that when I picked up a half inch Allen key socket set and socket swivels for changing the spark plugs. Oh well on the price difference. There's a few other parts I plan to pick up before I need to change everything. I need socket extensions and I plan to pick up some more titanium nuts and bolts to replace pieces in the engine bay. I may purchase the RR Racing carbon fiber intake package along with their AOS (air oil separator). I'll see how things go here in the next few weeks.
