your car cooled. Theres more to it when you go with a electric fan. You need to know the CFM that it pulls, i believe the z1 fan pulls close to 2200cfm, You can get a 16" fan from summit that pulls close to 2900cfm or even better you can get the 11" dual spal fans that pull close to 3000cfm and come with a shroud. But to be honest with you, stick to stock fan it does a great job of cooling the car and if im not mistaken you miss out only on 7hp or so.You can buy spals from JAYCORPTECH.COM Good luck.
