Good to hear -- I'll just use my working Mazda stock cap then. While shopping around for the Koyo, I was getting conflicting information from the various dealers I talked to regarding the necessity of buying the Koyo cap - some said it's OEM, others said you "need" the Koyo cap. Yeah, they "need" you to buy an extra and unnecessary part to fatten their bottom line.
