I am new to changing parts on my 07 Cordoba and not sure if I'm making a big mistake. I ordered a part online to replace the front 02 sensor and its part number 036906262J. The thing is when I removed the current one it had 036906262G, with the G being the only difference. I've seen a few others for sale that have both under the description but the one I bought doesn't mention the G part. The new one is a good bit longer and I hoped this is what the letter value referenced but I don't want to go through changing it if I'm just going to have to undo it all again. Any advice would be really helpful thanks.
