from amazon almost costing me to multiple faulty/incorrect parts, i managed to persevere and complete this install. bunch of videos out there using different parts, some show how to install but no links in the description, others give the links but dont show how to install. luckily this has both but if you have any questions or are in doubt please ask away!
in all seriousness the install itself wasnt that bad and it was nice to see how my intake valves are doing on my first direct injection engine. if i can do it so can you with the right tools! no tune necessary either.
