I recently picked up a 99 SVT convertible with 40,000 miles. The seller had a pick up and its tow kit back into his hood about a year ago and ruin it. He had a kid on the way, knew he was selling and threw on a colour match GT hood. Anyhow I'd like to install a cowl induction. The car has an 07 Vortech SC and just wondering whether a cowl hood would negatively impact air flow. If so what would be the best type/model available. The last mustang I owned was a 95 GT and I have a fair bit invested and don't wanna make the wrong call. Any advice would be appreciated.
