Got the wires and the plugs, but if I have the denso wire set without the connectors can I use the ones off the old wires. The connectors that I'm talking about are the one that have the letters on them.

Good question sir. Mine were replaced by the previous owner who warned me about the old brittle connectors that are still on there. You might have to get them separately. I believe DriftMotion carries them for a reasonable price.

are you talking about the clips where it connects to the ignition coil? I'm not liking what I'm hearing about those wires now that I just ordered them last week and waiting for them to arrive

Actually, I was incorrect the connectors do come with the wires. The snap on to the coil packs. You should be good to go.

Same here man! The clips were easy to replace too. The job went real smooth for me too.

I have always been a fan of doing what the manufacturer suggest when it comes to plugs. I used Denso twin ground, I think it was DENSP50745. But, it could also be other things as well like the connectors (to the coil packs) and/or the plug wires. If your car was like mine, the connectors were extremely brittle. In addition to the connector breaking up, the wires can pull out of the connector some exposing bare wire that can short out. I would start with those first: OEM plugs, plug connectors and plug wires. You can get the connectors on eBay for about $15 for 3 and a set of wires for about $30.

Here are the part # for the clips. 1953950010 = #1 coil (front)
1953246010 = # 2 coil (middle)
1953970010 = #3 coil (rear)
