I already searched and i didnt find anything . I am installing my MAC'S right now and I need to know if my O2 sensor wires need to be extended . I am installing them on a 94 Z28 . Thanks in advance

 

I just put MACs on my 95 TA and I needed 1 foot extensions. I got them from ls1 speed

 

Anyone have to have them extended on a single cat car ? Thanks

 

The driver's side reached on mine but it was close. The passenger side needed less than a foot extension. This was on a 95 single cat car.

 

I used extensions on both sides just to be safe, though like eddie said you can do it with only one.

 

how about woudl i need an 02 sensor for a 95 z28 with lts, and high flow cat?
thanks

 

My 95 TA is a single cat car. I didn't need a full foot of extension, it was just the smallest size I could find. I didn't want to make my own. I was about 2 inches short on the drivers side and maybe 5-6 inches short on the passenger side. The extra length was useful on the passenger side to keep the wires off the pipes.

 

I needed about 2 inches of extension with my AS&M's. Just a tip, don't try to splice them. It worked fine for about a month, now I get a constant SES light for them. I would of bought extensions in the first place but I had no time to get them whenever I found out that they were needed.

 

I did not need any extensions on my 94, so you may get lucky.

 

I didn't need any on my 95, originally a single cat car. I managed an extra inch out of the drivers side be slightly re-routing the wires where they came down.

 

You still need your precat o2 sensors(the ones in the headers) and for longtubes you need a one foot extension for each side.

 

wouldnt they burn up on the headers? how much will they cost and can you show me a link with which item to buy to be able to get everything at once?
thanks
