Dorman 03418 Turbocharger Stud Kit Compatible with Select Mazda Models

Quality is good. However, as others have said, some of the packages do not contain 3 studs and 3 bolts. Very strange.The studs were slightly longer than stock and the bolts were wider than the stock Mazdaspeed6. Could only use them on the Turbo to Downpipe connection. They would not fit on the Turbo to Exhaust Manifold connection. This was with aftermarket parts.Socket size is also 15mm, whereas stock is 14mm.

Lost one of the original studs/nuts. Used this kit to replace. Same size and thread pitch as the OEM 1987 Buick production. Only caveat is these studs are a 1/4" longer.

Make absolute sure you order more than you be need. Both packages in photo are completely sealed, yet somehow one package is missing a stud and one package is missing a nut. So weird.

These are an exact fit for the K03 turbo flange that comes on the VW Passats with the 1.8t engine, despite the fact they say "Mazda" on the box. Both the studs and nuts were great replacements for the OEM studs I have that were cross threaded to the exhaust. The only other thing I can think of worth noting is they are bright and shiny, not matte or black.

had to file to send back, one of the three was incorrect size, very noticeable without even opening package... the other two worked great. manufacturer said dont bother sending it back, we'll send you another 3. Thanks

I did not use these for their intended purpose. I had to replace some header to exhaust studs. Though long, I was able fix my issue and get the car through inspection.

Used these to replace my 03 5.9L cummins studs on the manifold and turbo. Fit perfect and seem strong enough to hold the turbo. Have been on the truck for about 9 months with no issues

Good strong studs, a touch longer than stock on a 01 Cummins. Bought a spare kit, don’t think I’ll ever need it.

I ordered three of these to have a complete replacement for my downpipe and my turbo to my manifold, but one stud was somehow lost. I assume it was open in storage before it was mailed to me since this one container looked to only have one stud in it till I dug through the package hoping to find the other two. Just disappointing to say the least.

Got all three studs but the package was open and the two too screws were no where to be found.. luckily we only needed the one

just 3 in the kit and i need 4 for kit turbo need buy another one

Good replacement for broken studs in a Mazdaspeed 3
