I just got these sensors for my 300C from US.
My dealer told me that they will not work for me.
By searching the forum I got the confirmation for that.
The sensors I got are # 56053030AC 315MHz ( justa as pictured )
but here in Europe we need the 433MHz model.
Too bad, I will have to pay $428.00 for my dealer to get the 433MHz sensors installed !
So I have 4pcs of brand new #56053030AC 315MHz US model
sensors available for $75.00USD shipped back to USA.
They have never been mounted on the wheel.
The mounting nuts and valve caps are also included.
You will not need anything else to install them to your wheels.
You can mail me and I would prefer PayPal.
Thank you for your time !
