Please Note: This graph shows the best case scenario and is the most amount of power regain we've seen.
Direct injection engines accumulate stubborn carbon deposits on intake valves because fuel sprays straight into the cylinder, bypassing the natural cleaning action of the intake tract. This buildup restricts airflow and reduces performance. Our walnut shell blasting service uses compressed air to propel fine walnut granules at high velocity through the intake ports, effectively removing carbon sludge. Walnut shells are the ideal choice—abrasive enough to dissolve heavy deposits yet soft enough to protect delicate valve seats and intake manifold surfaces from damage. Restore lost power, improve fuel economy, and extend engine life.
