| This is the throttle return spring that attaches to the linkage on the side of the throttle body. They are obsolete from Nissan and no longer available. We're in the process of doing a search to see if we can find a quality aftermarket source but until then we're stuck. Once we find an appropriate spring then the price will come way down accordingly. If you'd like to be on the list for a replacement spring at a more reasonable price, just send us an e-mail with a title "throttle return spring 75-83" We'll flag it and place it in a special folder. Once the springs become available again, we'll notify you along with a price. Be sure to include your phone number and year of z. Last update 11/10 |
