Waste of money. I had a charger with the 6.4 392 scat pack. On the charger forums lots of talk about catch cans. Just as many for it as against. Guys with over 150,000 miles no catch can, no problems. All the guys with them all they had to say was they dumped a few tablespoons of oil out off them at oil changes. I wouldn’t worry about needing one. Your car has run nine years without one. I think any oil build up in the intake is already done.
