Moroso

<p>For over half a century, Moroso Performance Products has been a cornerstone name in racing and high-performance automotive circles. Founded by Dick Moroso, the company began with a focus on solving real-world problems faced by racers, and that practical engineering philosophy continues to define the brand today. From weekend bracket racers to professional teams competing at the highest levels of motorsport, enthusiasts trust Moroso to deliver components that perform under the most demanding conditions.</p><h3>Engineering Excellence in Oiling Systems</h3><p>Moroso's reputation is perhaps most firmly established in the realm of engine lubrication. Their <a href="/466-moroso-engine-oil-pan-5562">engine oil pans</a> are legendary in racing communities, featuring baffling systems, windage trays, and kick-outs designed to maintain consistent oil pickup during hard acceleration, braking, and cornering. Whether building a road race car that experiences sustained lateral g-forces or a drag car that needs oil control during violent launches, Moroso offers application-specific solutions. Complementing their oil pan lineup, Moroso manufactures precision-engineered <a href="/466-moroso-engine-oil-pan-gasket-5436">engine oil pan gaskets</a> designed to seal properly even under extreme temperatures and vibration, preventing costly leaks that can end a race day prematurely.</p><h3>Ignition and Engine Management</h3><p>Beyond oiling systems, Moroso produces quality <a href="/466-moroso-spark-plug-wire-7224">spark plug wires</a> engineered to deliver consistent spark energy while resisting the heat and electromagnetic interference common in high-performance environments. Their ignition components feature low-resistance conductors and durable boots that maintain reliable connections even when routed near headers and other heat sources.</p><h3>Precision Engine Accessories</h3><p>The devil is in the details when building a competition engine, and Moroso understands this completely. Their <a href="/466-moroso-engine-oil-dipstick-10021">engine oil dipsticks</a> may seem like minor components, but they're designed with accuracy and durability in mind, helping engine builders and racers monitor oil levels precisely. For transmission specialists, Moroso also offers <a href="/466-moroso-automatic-transmission-valve-body-12200">automatic transmission valve bodies</a> and related components that support high-performance shifting and durability.</p><h3>A Complete Performance Ecosystem</h3><p>With thousands of products spanning oil systems, valve covers, air cleaners, cooling components, and fuel system equipment, Moroso offers a comprehensive catalog for performance builds. Their commitment to quality manufacturing and functional design has made them a fixture in engine shops, race trailers, and garages around the world. Whether you're chasing lap times, elapsed times, or simply building a reliable high-performance street machine, Moroso Performance Products provides the engineering solutions that serious enthusiasts demand.</p>

Product Details

Moroso spark plug indexing washers eliminate the tedious trial-and-error process of indexing spark plugs by allowing precise control over electrode orientation. Proper indexing positions the ground electrode away from the intake valve for improved flame propagation and performance. This 30-piece kit includes three different washer thicknesses to accommodate virtually any indexing requirement on 14mm tapered seat spark plugs.

Key Features:

  • Fits all 14mm spark plugs with 5/8" hex and tapered seats
  • Precision stamped from copper for superior heat transfer and sealing
  • Three thickness options: .010", .021", and .032" (10 washers of each size)
  • 30 washers per package provide enough for multiple engines or rebuilds
  • Eliminates the need to repeatedly install and remove plugs during indexing

Simply select the appropriate washer thickness to rotate the spark plug to the optimal position. The copper construction ensures reliable compression sealing while efficiently transferring heat away from the plug.
