I ordered a MAF from theautopartsstore.com. I installed it and it did not work. I went to the dealer and they ran codes which showed the MAF was still faulty. They advised the aftermarket MAF's do not work in Nissan vehicles. They ordered a factory MAF I installed it and it works perfectly. I spoke to the theautopartsstore who advised they could not return the part they could only give a core for it. I completed their online form and they called me. The rep on the phone was rude and advised they could not give me a core they could only exchange the part. So they sold me a faulty part that will never work and they refuse to acknowledge this. read full review »
