Just make sure it's a decent set. I bought a set or two off a susidiary of fel-pro. A couple days after the first install the hydraulic tensioner calved, had a small leak. So, I sent it back got another set and 10000kms later the guides gave up. I got ahold of fel-pro and they told me they weren't carrying the company anymore and basically to take it and shove it. There's a few companies in the states that make metal guides, I'd definitely reccomend getting a set. The guides are what fail 99% of the time.
IFS- Shouldn't that be a four letter word?
