I decided to put quality plugs into my 2000 Hyundai Elantra. I have almost 117,000 miles on it and drive it every day to work and for errands. I am happy with my purchase and will put these plugs in my 2 other cars if they fit. 5 years warranty...can't be beat.

Just pulled these plugs after a month. I was going crazy trying to figure out why my car sounded like a sewing machine and was hard starting in the morning. It started out with small starting problems and some loud ticking in the mornings when it was completely cool for about the first two weeks of use. It also developed a low rumble that sounded like an exhaust leak in the last two weeks of use. The rumble became a serious issue in the last two days. I thought back to switching out these plugs for the Platinum Denso's that I've had no problems with in the past. I reasearched a little on the internet and found that these Bosch Plugs do not do well with Japanese engines. My 04 Saturn Vue has an Acura 3.5L V-6 in it. Problem solved. Just pulled these plugs and replaced with the old Denso's that I held onto in case of emergency. It's running fine now. Will return them in the morning for a set of Denso's! Do not buy these if your engine is a Honda!

      Comments about Bosch Platinum+4 Spark Plug:

      This SparkPlugs are direct replacements for my car. Excellent product. A shame that I'm not that happy how my order was handled at the store. My parts were supposed to be ready and awaiting for me when I arrived to the store but that did not happen. I had to wait until the parts were picked up and delivered to me (10 Minutes). I would have done it faster by just going directly to the store.

      Comments about Bosch Platinum+4 Spark Plug:

      I installed these plugs in a 2003 Lexus ES300 that has 160k miles. I think the plugs I removed were original. I had to remove all the air ducting, the IACV, the throttle body and the intake plenium to get to the back three plugs. It took a long, long time. After removing all of that, I also installed new ignition coils on each plug. Didn't want to have to do that again. I think Bosch makes quality parts.

              I have a 1998 Blazer ZR2. I have 199,000. miles on it at this time.
              I installed the Bosch Platinum+4's in it at 98,000. mile and it has run great ever since. I got a little increase in my mileage. and the performance improved as well. I would recommend them to anyone.

              Comments about Bosch Platinum+4 Spark Plug:

              After 20,000 mi. with these plugs my 1996 Toy Tacoma first became hard to start, then misfired to the point that it was undriveable. I bought the Denso plugs that's recommended and replaced them now everything seems fine. I noticed a slight difference in the electrode of the three plugs on the drivers side of the eng. The drivers side plugs were eroded to almost a needle like shape .05mm dia. The passenger side plugs were 10 times the diameter and smooth flush with the insulator.

                Tried these twice. Works fine at first but after about 6 months of driving, some caused a low idle miss. Seems to be due to carbon residue and the small tip.

                    Comments about Bosch Platinum+4 Spark Plug:

                    This is the third set of Bosch Platinum +4 spark plugs I've purchased. It might have been more but they last a long time, typically 100k miles. Our '98 Toyota 4Runner with about 285k miles is on its second set. I noticed the gas mileage started falling below normal (18-21 mpg)so I changed the air filter with minimal effect. So I next bought another set of +4's and the mileage is averaging close to 20 all the time. The set I just bought is going into my wife's Highlander (you may detect a couple of patterns...) and, at 94k, hope to see some improvement, as it is falling behind the 4Runner. I just have to figure out how to get to the rear bank of cylinders. Bosch has an Iridium Fusion plug with the 4 grounding straps like the Platinum +4 but Advance doesn't carry them. I would like to try them if they start carrying them. Meanwhile, I'll stick with the Platinum +4's.

                    • Q:

                      I'm trying to get all the parts necessary in order to have my husbands 1992 V8 Mercedes Benz 500SEL Tuned up and ready for him when he returns to us from being away for over 9 months as a surprise. The car seems to be in bad shape from sitting for that long so if anyone can tell me the most cost effective way to go I'd appreciate it as unfortunately He has a mercedes but i am not made of money..lol
