{"product_id":"bbwq-85-0500","title":"K\u0026N 85-0500 Stubstack Air Horn","description":"STUBSTACK-HOLLEY MILLED CHOKE\u003chr\u003eThis K\u0026amp;N Stubstack is designed to be used on Holley 390-850 cfm square bore carbs (4150\/4160), that have had the choke horn milled off, but do not use an air cleaner. The full radius design helps to increase the airflow for drag racing. Will also hold down the base plate of a cold air scoop. Will not work with K\u0026amp;N Custom Chrome Racing Air Cleaners. The K\u0026amp;N Stubstack is designed to increase the airflow of carburetors by decreasing the restriction around the choke horn. Stubstacks fit inside the air cleaner housing and slide snugly down over the choke horn.\u003cul\u003e\n\u003cli\u003eFor Use Without An Air Cleaner\u003c\/li\u003e\n\u003cli\u003eWill Hold Down A Cold Air Scoop\u003c\/li\u003e\n\u003cli\u003eIncreases The Airflow by Reducing Restriction\u003c\/li\u003e\n\u003cli\u003eReduces Turbulence\u003c\/li\u003e\n\u003cli\u003eImproves Metering Accuracy\u003c\/li\u003e\n\u003cli\u003eMay Have To Alter Stub stack\u003c\/li\u003e\n\u003cli\u003ePolyurethane Material\u003c\/li\u003e\n\u003cli\u003eEasily Filed And Sanded\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K\u0026N","offers":[{"title":"Default Title","offer_id":40372628684939,"sku":"KAN85-0500","price":75.25,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0554\/5495\/7707\/files\/kan85-0500-546965c06441578626344cfb857c83678c83602d_9bc3fe28-65b4-414a-9247-44174f9add2e.jpg?v=1755616488","url":"https:\/\/jbspowercentre.com\/products\/bbwq-85-0500","provider":"JBs Power Centre","version":"1.0","type":"link"}
