Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator, or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.

Expert Answers
Is this correct for Ford focus st225
Yes, compatible with the Ford Focus ST225 Forge Motorsport turbo mounted recirculation valve.
Hi which spring should be used for a 911 996 turbo? Cheers
If the question relates to a fitted Forge Motorsport recirculation valve, then no; the correct replacement spring product code is FMDVSU110, related to the FMDV008 range recirculation valves we offer for the 911/966 model.
Otherwise the spring you referenced with product code FMSS114 does not fit and function in any other valve (stock or aftermarket) that could possibly be fitted to the 911/966 model.
Hello, will this fit Renault Megane 4 rs 1.8T with forge blow off valve upgrade?
Yes, the blue colour code FMSS114 being stock equivalent and the red FMSS114 for the stage 1 and stage 2 tuned Renault Megane RS 280 & 300 Mk4 models fitted with the blow off valve with product code FMDV23A.
Hello would this fit , an Ford fiesta ST180 product code : FMDVST180
Hi Ashley, thank you for contacting us.
Yes this spring will fit the FMDVST180.
Is this for the FMDVST180?
Hi Ashley, yes those spring types will fit that valve :)

This is the correct spring
Hi there I am looking for the small spring in the fmwrx301 as mines is broken an I am looking to replace it
Hello. You will need this spring (FMSS114) and to select 'Standard Spring' which is suitable for the FMWRX301
Hi, is this the correct (smaller of the 2 springs) for the megane 225 RS dump valve as mine has snapped?
Hi Richard, yes sir that the correct spring. Its either a Yellow or Blue blue depending if your car was mapped or not.
Hi.i have a Volvo S80 2.5t and it have a forge external like FMDVK04S. Its like that. I want a spring. The spring is 26mm and 25mm. Did you have something like that
Correct, single springs can be ordered under the product code FMSS114, and the complete spring tuning kit can be ordered under the product code FMDVTUN, both quoted spring products compatible with the valve with product code FMDVK04S.
Does this fit a Forge Motorsport Subaru WRX blow off valve?
Yes this the FMSS114 (standard option) is one of two internal springs found in the Forge Motorsport win piston dump valves we offer for the Forge Motorsport twin piston blow off valves (more specifically Subaru blow off valve valve product codes FMWRX301, FMDVSUB01, FMDVV5012, FMDVV4010 and FMDVK013A). The FMSS114 is the smaller of the two internal springs, otherwise referred to as the idle spring.
If needed the main boost spring (larger of the two internal springs) for the range of Subaru valves quoted can be ordered under the product code FMDVSU110, the blue option being the fitted spring for standard engines.
