Free of complex emissions traps like DPF, it’s a pure performance beast—with one massive exception: the EGR system.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eOver time, the factory EGR dumps burning-hot, abrasive soot into your clean intake, choking your engine with power-robbing sludge. Worse, the factory cooler is prone to internal cracks that leak coolant into your cylinders—often leading to catastrophic blown head gaskets.\u003c\/li\u003e\n\u003cli\u003eThis LBZ EGR Delete Kit completely removes this bottleneck. allows your LBZ to breathe pure, cold air, extending engine life and lowering operating temperatures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003carticle class=\"4ever-article\"\u003e\u003cstrong\u003e\u003cspan data-type=\"text\"\u003e\u003cspan data-type=\"leaf\"\u003eKey Features\u003c\/span\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/article\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003ePremium Billet Construction: CNC-machined anodized black aluminum blocks off the intake ports perfectly,leak-free seal under high boost.\u003c\/li\u003e\n\u003cli\u003eLower EGTs \u0026amp; Coolant Temperatures: By completely bypassing and deleting the hot EGR cooler, you drop EGTs and take the thermal load off your truck’s cooling system.\u003c\/li\u003e\n\u003cli\u003eQuicker Turbo Spool-Up: Freeing up your intake restriction allows clean, fresh air to flow without turbulance.

The LLY requires bypassing a buried cooler and has different flange shapes. The LBZ kit includes dual billet block-off plates with built-in O-ring seals that fit the LBZ’s specific dual-intake design perfectly. Always buy the kit matching your exact model year.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will I get a Check Engine Light on my LBZ after installing this?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes. Removing the EGR valve on an LBZ will throw emission-related diagnostic codes. You must use an aftermarket tuner with an EGR-delete tune to disable the codes and prevent the truck from going into \"limp mode.\"\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why does this kit include an \"Intake Support Bracket\"?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Removing the bulky factory EGR cooler also removes the stock support points for your intake plumbing. Our kit includes a heavy-duty stainless steel support bracket to keep your intake tube secured and prevent vibration-induced stress on your engine fittings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse my factory gaskets?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: No need. Our kit includes high-temperature, fuel-resistant O-ring seals pre-fitted into the billet aluminum intake block-off plates. This guarantees a far better, more reliable pressure seal than old, compressed factory gaskets.\u003c\/p\u003e","brand":"True American Diesel","offers":[{"title":"Default Title","offer_id":47118862254268,"sku":"ER-0024","price":126.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/4101\/8044\/files\/1_92f3fbe5-f058-4f6f-b66f-2303b19e3acb.jpg?v=1786464389","url":"https:\/\/trueamericandiesel.com\/products\/egr-valve-cooler-delete-kit-for-chevy-silverado-serra-2500-3500-hd-gmc-6-6l-duramax-lbz-2006-2007","provider":"TrueAmericanDiesel","version":"1.0","type":"link"}
