Great product, saved me 1200$. My old ones were clogged and stuck. New ones were 150$ a piece! This kit provides everything thing you need to rebuild them to new. After pulling the old filters, cleaning them with carb cleaner while tapping on them to unstick, replacing filters, new caps, and o-rings , they work as new. Well worth the cost and quality parts. Would definitely recommend. Fit 2008 TBSS intake injectors.
