Review on Premium Ignition Coils for 2002-2008 Nissan Sentra & Altima - Pack of 4 Coils by AUTOSAVER88 by Martin Alvarez

I bought these to replace my 05 Sentra Set Spec V. One of the original coils gave an error code. No wonder the car has 221,000 miles on it. The delivery is excellent, the parts came the next day. Installs in about 10-15 minutes. The car started, runs great, no misfires. It's only been a week with no problems. Just a tip, label your old coils by noting the ones that don't fit. The OBD-II code reader will tell you which package is faulty. Keep the old good ones in case one of the new ones goes bad. They also sell kits to replace the tube and the internal spring that contacts between the coil and the plug. Sometimes they deteriorate to coil. I decided to do all 4 at the same time because I figured given the mileage of the car that if one goes the others might not be far behind. These reels are great value for money. Will update all questions.
