What did you do to your Supra today?

How often are you supposed to change plugs and coils?

70+ track days, 600whp+, original coils. No reason to change them unless you are having issues, although I do understand preventative maintenance.

Spark plugs are maintenance items not the coils. Wait til one coil goes out and you can change them all out the same time if you like.

Thanks. Good to know.

Quick note for the MHD flex fuel kit, highly recommend getting a pick tool set with bends and/or hooks before starting

This dude has the only youtube video installing the MHD kit on a Supra, and at 3:45 glosses over unclipping the connector which was the longest part of the install for me. On other b58 cars, the connector is easy access on top, but on the Supra they put it behind the DME Splash Shield.



You will need a hook tool to grab the bottom side of this connector. I couldn't get a good angle to put pressure on the bottom squeeze tab

To get to these panel mount releases, I had to use a straight pick for the top two and a 45 deg bent pick for the bottom one. Top two you push down, bottom one you pull up.

There seems to be two ways to mount the ethanol sensor, you can either mount it high or low. But I wasn't able to mount it low without stressing the DME harness. Maybe you need to unplug all the DME connectors to mount it that way, and then put them all back. (?)

Oil and filter change today.

You can also mount it behind by the firewall. That is how I did it back when I used the same fittings.

I was doing 2-3 track days a month for 10 months out of the year for ~3years with the car, plus being at Tennessee Intl Raceway every weekend when not at the track.

I'd say the increased stress from the driving did it in. It's not as bad as I've seen, but it is a wear item.

I meant more along the lines of what driving conditions made you hear this clunk?

Initial takeoff.

Initial takeoff.

I've got a clunk in the rear that only happens at low speeds (under 8 mph) with some steering angle applied and I've been trying to figure out what it might be. Dealer says it's the tires "skipping" on the pavement which I don't believe for a second. lol

Was this with the MHD pnp kit? I dont remember the wires being long enough to put it there...

Good call out, no it was not. However I am about to install the MHD pnp kit on my M240i so I will let you know.

I actually hope it is because the M240i has a totally different hardline at the shock tower that does not have a 90* bend like the Supra does. It terminates vertical and lower.

I mounted mine in the same spot as @razorlab. I have the mhd kit. Can’t even tell it’s there. Plenty of wire to do it.

Did the audio “upgrade” still need to get zip ties so I can get the mesh on there but overall I am happy with my work.

Gaping @tadda holes are what we officially call them. You could also add some black mesh or black out that foam.

If you're lazy like me, I just seated the trim piece half an inch away from the box, on top of the carpet, to let the sound escape.

Went for a drive to visit my son on Chirstmas day and weird things happened.

I had a CEL pop up the day before - see image above - which I cleared that night. When I jumped in my car today the CEL appeared again straight away which is fine but... when I got home to check the codes, there were none reported.

And after starting the car again one more time, the CEL didn't come back.

Just over 6000 miles on my 2025 Supra that included track days a Barber, Sebring and Daytona. Changed the oil & filter and flushed the brakes. I was kind of surprised at how good the used oil and the brake fluid looked.
