Moroso 73688 Ultra 40 Spark Plug Wires BBC 454 Chevy HEI Distributor 454 7.4L

Moroso Ultra 40 Unsleeved Plug Wire Set

Big Block Chevy, Over Valve Cover, 8.65mm

Red, 180° Boots, HEI

Ultra 40 un-sleeved wires are a cost effective version of the Ultra 40 Race Wire without heat sleeving.

Wires feature a Kevlar core, four times stronger than other aramid fiber cores, that increases the tensile strength of the wire while reducing its center diameter.

This allows for the surrounding insulation to be thicker, resulting in greater dielectric strength.

With only 40-ohms of resistance per foot these wires will increase power and fuel efficiency by bringing more spark to the plug.

RFI/EMI resistant to eliminate stereo feedback or ignition interference.

We are happy to combine shipping on Ebay auctions when possible. Normally it will be the highest shipping amount plus half the shipping amount on other items, sometimes better on orders of small items. Some items are not combined due to size or weight such as crankshafts, torque converters, radiators, cylinder heads, etc. On multiple item purchases the shipping amount is not figured automatically during checkout so please request a new invoice or wait for us to send a combined invoice so we can adjust the total.

We may have auctions that state free shipping when purchased with certain items. If purchasing items with free shipping, please request a new invoice before paying. The shipping amount is not figured automatically during checkout. We are unable to refund your Paypal once payment has been sent. If you have any doubt what your shipping will be please feel free to message us through the ebay message system.
