83mm extension housing for the Ultimate Racing Cold Air Intake for '02-'07 WRX/STI. Replaces the undersized stock MAF housing to prevent max'ing the MAF out on GT35R and bigger turbos. Good for 560whp+. Includes high-quality 83mm MAF housing, AEM DryFlow filter, and silicone adaptor coupler.
Requires a retune after installation.
