Halltech TRAP (questions about year)
Might want to ask this question on one of the dedicated 'Corvette forums', use Google to find them.
BTW, I'd probably go for the Donaldson Blackwing. The filter is far superior as it uses a synthetic weave instead of cotton. It doesn't require oiling. Only cleaing once in a while, it even has an indicator to tell you when to do this. And will still flow as much air as any other out there.
Remember filtering, is the prime objective of an air filter.
You'll also probably see Vara-ram mentioned quite a bit. Personally I'd stay away from it. Yes it can produce some pretty results (no where near as good as Vara-ram claim) but the whole design is flawed and the filters are pretty useless at filtering.
