We have seen many heads and engines damaged as a result of the weak and failure-prone Intake Valve Springs on these motors. The Springs are replaced with a Heavy Duty High-Rate Valve Spring set featuring a single spring setup for the Intake Valve Springs, a dual-spring setup for the Exhaust Valve Springs, and Titanium Spring Retainers. The Heavy Duty, High-Rate Springs and Titanium Spring Retainers allow for high-RPM operation of this motor by reducing the weight of the Valve, Spring, and Retainer combo. Reducing the weight of the combo reduces the amount of inertia required to propel the valves and this allows for a more stable and longer lasting valvetrain. Just the long list of advantages above was enough to convince us to run these parts in all of our JHM Rebuilt Heads. Since these upgraded spring kits cost about the same as OEM springs ONLY, upgrading to these Heavy Duty, lightweight, and more durable components was a no-brainer.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eNOTE\u003c\/b\u003e: This picture also shows our brand new, JHM Heavy Duty Coated Intake and Exhaust Valves which are included in our Rebuilt Cylinder Heads or available for sale separately.\u003cb\u003eOur Heavy Duty High-Rate Valve Spring and Performance Titanium Retainer Set Includes the Following:\u003c\/b\u003e\u003cbr\u003e- 24x High-Rate Intake Valve Springs\u003cbr\u003e- 16x High-Rate Exhaust Valve Dual Spring Pairs\u003cbr\u003e- 16x Dual Spring Spacers\u003cbr\u003e- 40x Titanium Retainers\u003cbr\u003e\u003cbr\u003eFor shipping quotes, please sign in or create an account then put the items you want in your shopping cart and proceed to checkout.\u003c\/p\u003e    \u003cp\u003e \u003c\/p\u003e    \u003ch4\u003eCompatibility\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eChassis\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eS4\u003c\/td\u003e\n\u003ctd\u003eB6 (2003-2005)\u003c\/td\u003e\n\u003ctd\u003e4.2l V8 40v\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eS4\u003c\/td\u003e\n\u003ctd\u003eB7 (2005.5-2009)\u003c\/td\u003e\n\u003ctd\u003e4.2l V8 40v\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eallroad\u003c\/td\u003e\n\u003ctd\u003eC5 (2001-2005)\u003c\/td\u003e\n\u003ctd\u003e4.2l V8 40v\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eFeel free to contact us at info@mlperformance.co.uk should you wish to double check!\u003c\/p\u003e    \u003cp\u003e \u003c\/p\u003e    \u003ch4\u003eCompatibility Check\u003c\/h4\u003e\u003cp\u003eTo ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch.
