I have a MSD Dis 2 Ignition Module up for grabs. For those of you that dont know what it is or what it does it puts out a high spark energy and voltage and gives u multiple sparks. This one is cool from all the others cuz u actually get to control it and costomise it to your own specific needs like RPM range Starting and Idle Throttle response top end power retard and much more. It was only used on my car for about 2 months cuz i liked it so much that i bought the racing version for my car with all the upgrades i had. For the 420A engines ur also going to need the tach adapter which i'll throw in for free and that'll cost you about $60 bucks. So you can get them both for just $200 dollars in great condition or you can get one for about $320 which is what i bought mine for. So if your interested or have any questions email me at TruPlaya2258@yahoo.com
