Euro 4 & 5 catalysts For Easy Replacement ME TAL CORE Prolonged life-expectancy than comparable DOC, SCR or POC ceramic substrates to keep you on the road longer. Reduced back-pressure compared with ceramic substrates translating to increased fuel efficiency. System w/SCR BUILD TO LAST The substrates are locked in place by spaced grooves, minimizing the risk of slippage or unwindage from the mantle. The metallic core does not crack compared to ceramic substrates. PERFECT FIT Manufactured accroding to very tight geometric tolerances. The replacement catalysts are offered in sizes for best fit of your particular application.
