The open design helps enhance air flow into the plenum, which may translate to more consistent response during spirited driving. Remember, results depend on your overall setup, including manifold, carb tuning, and exhaust configuration.\u003c\/p\u003e\n\u003ch3\u003eInstallation Tips\u003c\/h3\u003e\n\u003cp\u003eBefore installation, verify your carburetor base pattern matches the Holley 4150\/4160 square-bore design. With two thickness options, you can fine-tune the spacer height to accommodate your gasket stack and manifold height, aiming for a clean seal and proper air seal between components.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What carburetors is this spacer compatible with?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Compatible with Holley 4150\/4160 square-bore 4-barrel carbs and similar brands.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What does the set include and what are the materials?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Phenolic spacer; includes 1 spacer, 2 gaskets, and mounting hardware.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"SHLPDFM","offers":[{"title":"Default Title","offer_id":42468787716181,"sku":"B0B495Y39B","price":39.15,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/3270\/4597\/files\/shlpdfm-1set-black-carb-spacer.jpg?v=1778080807","url":"https:\/\/plentytorque.co.uk\/products\/shlpdfm-1-set-black-phenolic-carb-spacer-for-holley-4150-4160-4bbl","provider":"PlentyTorque","version":"1.0","type":"link"}
