Those will work, but I wouldn't run them on a boosted motor. The reason being is they have been known to dump oil into the exaust. Also have been known to keep one from passing smog ( not every one on here deals with that, just saying ). Catch cans have always been the way to go, and to pass the smog route intake pipe before turbo with air filter and from catch can to turbo air filter pipe. If run with just a filter they say you are just venting.
