1/22/12 Just a quick warning: this company may not be as legitimate as the VW community thinks. Several Mazda websites do not have fond memories of this particular company. I’ll have to find more information…Stay away for now.
Nothing has proven to be as good as just replacing or checking the cam follower periodically. I’ve been lucky with the wear so it’s far easier for me to not worry about it. Unfortunately, there are a variety of factors that contribute to what kind of wear you see and your experience may vary wildly. Keep on top of your oil changes and keep track of your follower wear!
For the past few months, the company HPFP Upgrade has been working on creating a cam follower that is more durable than the oem piece. Testing is now practically complete. I’m guessing that they are in production right now with a probable February release. HPFP Upgrade is a relatively new (to me) company that focuses on the fueling system for various direction injection cars.
There’s been a good deal of anticipation regarding this product. Any product that can help with the FSI’s follower problem is welcome. The company states that it has achieved an increase in durability through the use of hard chroming. By creating a surface with less friction, there is less wear between the follower and cam. Testing supposedly confirms their claims. In addition to the new surface material, the oil flow holes were relocated to the sides. Information is limited right now as the company has yet to officially release the product.

Of course, the product is untested by the mass public and details such as warranty have yet to be hashed out. There are still unanswered questions. How will the relocation of the oil holes affect things and how durable will the follower and hard chrome finish really be in real life application? HPFP Upgrade asserts that the the new finish is much tougher than the OEM DLC coated follower and slicker as well. They also say that the relocation of the oiling holes also has nothing but positive effects, although their reasoning is yet to be seen. The company seems to have done its homework, field testing a few units with favorable results. So far better than another company that just made the follower thicker and omitted the DLC coating…*cough*kmd*cough*. The design is superficially similar to followers used by Mazda.
I’m following this product quite closely and will probably try it out when it does finally get released.
Here’s a thread on the MKV forum with a few details but it unfortunately turns into a flame war in a page or so. Upgraded FSI Cam Follower
