It could be something else other then core type I just couldn't find what exactly to call it heh.
TUBE AND FINBenefits:low cost low weight
Disadvantages:"effective" lower efficiency compared to bar and plate can be poor quality dependant on supplier is a little more awkward to modify core size some brands are plastic sealed at ends and have limits on welding techniques
BAR AND PLATEBenefits:35% greater heat sink capability (meaning you effectively COULD have a SMALLER intercooler when compared to the tube and fin) Generally known as the "better product" easy to modify size and re weld
Disadvantages:weight cost some limitation in sizes The tube and fin is a common everyday upgrade due to its low cost.The bar and plate is far superior BUT it costs more.
I got that from: How an Intercooler Works
