BMW - E30 M3, AFM to Manifold Intake Boot

$54.99

Purchase BMW - E30 M3, AFM to Manifold Intake Boot

BMW - E30 M3, AFM to Manifold Intake Boot Is your E30 M3 stumbling when you first give it gas? A little hard to start? Maybe its idling funny, or not at all... or it smoothes out quickly as it warms up?
These are all symptoms that could be caused by a cracked or leaky intake manifold elbow. A leak after the AFM can be fatal to your S14, causing it to run lean and experience destructive detonation (sometimes too quiet and slow to hear by ear).

If you suspect your intake elbow may be original, it may be best to replace it before it cracks at the worst time. It is close to impossible to see a legitimately leaky elbow with the naked eye. At this price, we recommend you have an extra spare, especially if you track your car.

    VAC Tech tips:
    -We recomend replacing this intake hose with OEM Vs. an aftermarket piece: the OEM is designed to flex and twist the correct amount. Aftermarket hoses like the popular Samco (that we like a lot for other applications) will not flex properly on the E30 M3 intake box and can cause the weak welds to snap or crack where the airbox is mounted to the chassis.
    -A 'Smoke Test' is the reliable way to check for leaks of this elbow. Many times a small leak is impossible to detect with the eye and can cause intermittent problems. Most professional auto repair locations have a Smoke Test Machine.
