Designed specifically for turbocharged and high-RPM engines, these springs feature a seat pressure of 93 lbs at 1.320 inches and an open pressure of 238 lbs at 0.820 inches, ensuring optimal valvetrain stability even beyond 11,000 rpm. Crafted from super-clean chrome-silicone wire milled in Japan, each spring undergoes rigorous manufacturing processes including heat treatment, shot-peening, chemical polishing, and nitriding to maximize strength, durability, and resistance to load loss. These features make the springs ideal for use with high-lift camshafts and in extreme engine conditions, providing reliable valve control during prolonged high-RPM operation. The dual-spring design, with inner and outer springs fit together with a slight interference fit, prevents valve float and maintains consistent pressure at extreme engine speeds. Each set contains 16 springs, meticulously manufactured and inspected to meet championship-level racing standards. Whether installed on Honda Civics from 1994 to 2000 or Acura Integras from 1998 to 2001, these springs deliver superior performance, durability, and stability for demanding motorsport environments. Skunk2’s dedication to quality ensures these springs are robust enough for extreme racing conditions, making them a top choice for professional engine builders and enthusiasts seeking maximum power and reliability at high RPMs. Engineered with precision and tested extensively, the Skunk2 Pro Series XP Valve Spring Set is designed to handle the stresses of championship-level racing, providing a significant upgrade over stock components.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003ePrevents valve float and maintains valvetrain stability above 10,000 rpm\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eManufactured from super-clean chrome-silicone wire for durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOpen pressure of 238 lbs at 0.820 inches for high-RPM performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSeat pressure of 93 lbs at 1.320 inches for reliable seat contact\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCoil bind height set at 0.718 inches to accommodate high-lift camshafts\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSet includes 16 springs, suitable for Honda Civic and Acura Integra models\u003c\/li\u003e\u003c\/ul\u003e\n\n\u003cp\u003eFitment:\n\u003cbr\u003e1992 Acura Integra GS-R\n\u003cbr\u003e1993 Acura Integra GS-R\n\u003cbr\u003e1994 Acura Integra GS-R\n\u003cbr\u003e1994 Honda Civic del Sol VTEC\n\u003cbr\u003e1995 Acura Integra GS-R\n\u003cbr\u003e1995 Honda Civic del Sol VTEC\n\u003cbr\u003e1996 Acura Integra GS-R\n\u003cbr\u003e1996 Honda Civic del Sol VTEC\n\u003cbr\u003e1997 Acura Integra GS-R\n\u003cbr\u003e1997 Acura Integra Type R\n\u003cbr\u003e1997 Honda Civic del Sol VTEC\n\u003cbr\u003e1998 Acura Integra GS-R\n\u003cbr\u003e1998 Acura Integra Type R\n\u003cbr\u003e1999 Acura Integra GS-R\n\u003cbr\u003e1999 Honda Civic Si\n\u003cbr\u003e2000 Acura Integra GS-R\n\u003cbr\u003e2000 Acura Integra Type R\n\u003cbr\u003e2000 Honda Civic Si\n\u003cbr\u003e2001 Acura Integra GS-R\n\u003cbr\u003e2001 Acura Integra Type R\u003c\/p\u003e","brand":"Skunk2 Racing","offers":[{"title":"Default Title","offer_id":46078361370823,"sku":"skk311-05-7350","price":410.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/2277\/5751\/files\/aa47af013ad5fd4f5059a6fdcbd45b7b.jpg?v=1768175024","url":"https:\/\/mainstreeteshop.com\/products\/skunk2-pro-series-honda-acura-b-series-vtec-xp-valve-spring-set-high-rpm-race-grade-dual-springs","provider":"MAIN STREET ESHOP","version":"1.0","type":"link"}
