X15 EGR tuneup

[tree98]

all easy to get to, can't remember exactly what tools you'll need but nothing exotic. I didn't bother to clean any of them i just replaced them with new. I also replaced the short steel tube from the exhaust manifold to the exhaust back pressure sensor because they get Carboned up inside. If you decide to do that you'll likely need a little help from the fire wrench to get it unscrewed from the manifold.
