Q: Which air intake would you use? I have a 2006 Nissan Sentra 1.8 which do you think is the best to us a Fujita, injen, or a JWT popcharger? I am looking at all three let me know which is the best? Also how will they hold up in rainy weather? Thanks.
A: Any air intake taking in cold air is better than hot air inside the engine compartment. Nismo uses a Foam Water Excluder. Other inferior designs do not have a safety device to keep water from entering the engine. First off do not drive into deep water! second buy a air intake that takes in cold air. Third any performance increase will be being able to hear the intake sound there really is not much power gain unless you also make the exhaust flow more headers and cat back system and Replace the computer with a JWT ecm that will use the more intake and exhaust flow.
