The rubber boot between the MAF and throttle body
This rubber intake boot carries air from the mass air flow sensor to the throttle body. This boot can tear and crack with age which can result in performance issues. If this boot cracks air is allowed to get into the intake past the mass air flow sensor and is unmeasured. This unmeasured air can cause misfires or other abnormal engine behavior.
