You're absolutely wrong on this one. Blehh was 100% correct. Any aftermarket intake (and possibly but less drastically certain aftermarket filters) on these cars requires a tune due to airflow differences.

Your friend might have had it on his car for a year with "no issues", but no apparent issues does not mean that he wasn't putting his engine at severe risk. As Blehh said, you're basically hoping that your ecu will adapt the fuel mappings to compensate for the lean conditions that intake will cause.

Again, no apparent issues does not mean that your car is not at severe detonation risk due to running lean.
