When it comes to building and customizing our muscle cars, every little bit helps. When that little bit amounts to a bigger chunk, then it becomes even better, and MSD Performance is offering up some of those bigger chunks for seven weeks with their Lucky 7 promotion. For seven weeks, when you purchase a selected MSD product from an authorized dealer, you get a selected free part along with your purchase.

As an added bonus, by submitting your rebate to MSD you’re automatically entered to win a trip for two to the 2013 SEMA trade show in Las Vegas this fall. That gives you seven chances to enter, and the more rebates you send in, the better your chances are. But you know what they say: you can’t win if you don’t enter, and you can’t get your free parts without sending in your rebate.

This week, MSD is offering up a free LS Super Conductor Spark Plug Wire Set with the purchase of an MSD Multi Spark LS Coil Set. If you’re replacing your LS Coils, then why not replace the spark plug wires at the same time? When you purchase your coils from an authorized MSD reseller, the spark plug wires are on MSD for the fifth week of their Lucky 7 Rebates.

With all of the LS engine swaps being done on classic musclecars these days, MSD provides another way to upgrade your swap with an upgrade to the ignition system. Even for your stock LS applications, the MSD LS coils are designed to give you improved energy and voltage output, replacing the factory GM coils without any modifications to the wiring because they’re a direct plug in.

With the increase in voltage and performance from these multiple spark coils, you can expect better throttle response along with the higher energy that these coils produce. Add to that the improved combustion process and you’ll also see increased performance at higher rpms, as well as quick starts and a smoother idle.

With the improvements in the spark energy, it only makes sense to upgrade the factory spark plug wires as well. The MSD LS Super Conductor spark plug wire set is a great complement to the coils because they’re designed to handle the increase voltage and energy. The 8.5mm wires feature a double crimp – one on the conductor and a second on the sleeve itself, assuring a positive crimp on the spark plug wires.

And with the short length of the LS spark plug wires, you can count on low resistance, and increased protection against Electro Magnetic Interference (EMI) to isolate the spark energy inside the wire where it belongs. So don’t delay that LS ignition upgrade any longer, and get a free set of LS Super Conductor Spark Plug Wires with the purchase of the MSD Multi Spark LS Coil Set included in this, the fifth week, of MSD’s Lucky 7 Rebate Program. But just as we mentioned in the first week’s offer from MSD, you have to send in your rebate in order to get your free LS Super Conductor Wire Set, and also to be automatically entered in the SEMA 2013 drawing.

Do you want to know what the Lucky 7 offer is for next week? We want to know, too, but unfortunately MSD isn’t talking. Just like us, you’ll have to wait until next week to find out, and we’ll bring it to you as soon as we find out! So check back with us each week and we’ll keep you in the loop!
