Most of the time people love to throw ranges like 5 to 15 rwhp. But never specify that 5 rwhp is going to be avg for NA cars and 15 rwhp is going to be avg for supercharged cars. With that being said, I have four intakes to talk about. And no lets not bring up those race only hp at the top end torq loss at the bottom end intakes either, I'm sure you know the ones that I'm refering too. Anyway on with the comparison for intakes that will fit on to 96-98 GT's.Ford Racing Performance Parts Intake  <a href="http://www.fordracingparts.com/parts/part_details.asp?PartKeyField=3330" target="_blank">http://www.fordracingparts.com/parts/part_details.asp?PartKeyField=3330</a>Cost: $1,695.00Ford Advertised Flywheel Horse Power: 35 Requires installation hardware kit Cost: $325 (probably cheaper somewhere else)Sean Hyland Motorsports Comments  <a href="http://www.seanhylandmotorsport.com/online/product_info.php?cPath=30&products_id=192" target="_blank">http://www.seanhylandmotorsport.com/online/product_info.php?cPath=30&products_id=192</a>-Comments: "Large diameter primary runners produce a significant horsepower increase in the 4000 to 6000 RPM range without loss or mid-range torque."

Tuning may be required due to the increase of airflow from the Non-PI Intake manifold." "The new kit uses specialized adapter plates, a modified intake manifold (un-modified manifold will not clear stock hood), and gaskets to make it a direct bolt on with limited alterations."Total Cost: $499 Total Possible Horse power Flywheel hp 40+ off stock applications. need to call and find out what "Stock Applications" mean.Horse power per dollar spent: $12.48PI Intake, using RTV sealant       <a href="http://www.fordracingparts.com/parts/part_details.asp?PartKeyField=6125" target="_blank">http://www.fordracingparts.com/parts/part_details.asp?PartKeyField=6125</a>Cost: $209Non Advertised but forum agreed apon flywheel horse power: 20Comments: "Additional modifications and parts required"Total Cost: $209 + sealantTotal possible horse power: 20Horse power per dollar spent: $10.45P-51 Intake Not sure if in can be fitted on 96-98 GT's.
