            Great bang for your buck

            I can definetly say that these plugs have improved performance but with the combination of NSK plugs new Omix spark plug wires and a new Airaid air filter the performance on my 2011 JKU has greatly increased. *** Word of advice... no need to route plug wires back behind the block. Run them over the engine. The wires come with heat shields.
