Built from composite compounds with a protective nitrile surface, it raises the carb slightly off the manifold to interrupt heat transfer and limit boil-off in the float bowls after engine shutdown. The kit ships with longer carb studs for secure mounting and fits many common Chevy and Ford V8 applications as well as specified Edelbrock and Holley models.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this gasket reduce fuel boiling and percolation?\u003c\/h3\u003e\n\u003cp\u003eThe gasket creates a thermal break between the hot intake manifold and the carburetor, slowing heat conduction into the float bowls. That reduced heat lowers the chance of fuel vaporizing under the carb between runs, improving cold starts and drivability after stop periods. The open‑center dual plane design also helps maintain stable airflow through square‑bore plenum setups.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16\" thickness creates a measurable gap to limit heat transfer\u003c\/li\u003e\n  \u003cli\u003eNitrile coating resists fuel exposure and oil soak\u003c\/li\u003e\n  \u003cli\u003eOpen‑center dual plane form maintains plenum airflow balance\u003c\/li\u003e\n  \u003cli\u003eIncluded extended studs ensure proper clearance and sealing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich engines and carburetors will this spacer fit?\u003c\/h3\u003e\n\u003cp\u003eThis gasket is prepared for square‑bore flange carburetors commonly found on classic V8 engines.

The Camotokiit 9265 heat insulator gasket is ideal for restorers, street‑rod builders and performance enthusiasts who run Holley‑style or Edelbrock square‑bore carburetors on classic Chevy and Ford V8s and want to reduce post‑shutdown vapor lock, improve cold‑start reliability, and protect fuel integrity under high under‑hood temperatures. It’s suited for anyone seeking a straightforward direct replacement that preserves carburetor geometry while adding thermal protection without extensive modifications.\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: Will this gasket work with my Holley 4150 carburetor?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it’s designed for Holley 4150‑style square‑bore carbs and Edelbrock square‑bore models; verify flange type and part 9265 cross‑reference.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need different studs or hardware to install it?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No extra purchase needed; the kit includes extended carburetor studs for proper clearance and secure installation.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Camotokiit","offers":[{"title":"Default Title","offer_id":48085566357662,"sku":"B0FPWZWRQ1","price":37.22,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/camotokiit-front-view-gasket-packaging.jpg?v=1785873442","url":"https:\/\/northtrailauto.ca\/products\/camotokiit-engine-carburetor-heat-insulator-gasket-spacer-5-16-thick-nitrile-coated-with-extended-studs","provider":"North Trail Auto","version":"1.0","type":"link"}
