I recently bought a Protoxide intercooler for my Grande Punto Tjet. Pulled off the bumper and took off the stock intercooler, only to find that there was nowhere to secure the intercooler!! I didn't receive any brackets or anything that would make it fit. Has anyone installed a Protoxide intercooler on their Tjet?

f you are referring to this one: https://www.protoxide.eu/en/air-air-intercooler/1511-front-intercooler-kit-grandepunto-abarth.html

You can see they are using regular hardware store perforated steel strip.
If it didn't come with those you payed quite a steep price.
