So it was time for me to replace my spark plugs and wires.

 

I was currently running a set of MSD wires (over 6 years of abuse) and E3 Spark Plugs (test set) so I started my search.

 

For spark plugs it was easy...I went back to my Tried and True NGK Iridium spark plugs since I have found no plug to perform better based on my own personal testing. I increased the OEM gap of 0.060inch to 0.070inch and in they went.

 

Now I wanted a better spark plug wire that what I currently had. The MSD are great wires with about 50ohms per foot of resistance but I wanted better! Afterall, the more you can lower the resistance, the more intense the spark will be. The more intense the spark is, the more fuel is burned and the more powerful the explosion which results in more power and better fuel economy.

 

My Search led me to Granatelli with their "Zero" resistance wires. I ordered a set and validated their claim. Here are the pics;

 

First the MSD, 38ohms of resistance:


Now the Granatelli, 0ohms of resistance:


The best part is even with a solid core there is absolutely no EMI or RFI! I went for a test drive and you can definitely notice a performance increase. I did notice about 0.5-1L/100km fuel mileage increase...when you are not driving it like a race truck! I have been running/testing them since November 2014 and I am totally pleased!



Here is a video link that explains the wires a bit more!

Next on my list will be their coils...but not right now!



So why not get yourself a set today!


Later,

I used to run MSD ignition and / wires on my old 454 Chevy drag car. Loved them...

But wow those seems to be even better!!! Anything to help with power/performance I'm soooo in.
