Bosch FGR8DQP Platinum Spark Plug Review

They are suitable, but not for all applications. Only they are more suitable for European cars than for Asian ones. So after a frustrating couple of months I switched back to NGK spark plugs for my Mazda. Bosch is a well known quality brand and my disappointment was entirely due to my own mistake in choosing. Lesson learned, I definitely recommend them for proper use.

I really like these candles. This is my second sentence. The first set exceeded 100,000, you can immediately see the increase in accelerator pedal response time. Enough that I have to get used to the gas pedal again when starting off. This is in my 2005 Tundra 4WD Double Cab. (Yes, I've read on Tundra blogs that Bosch shouldn't be used in Toyota. I've had a Toyota since 1985 and prefer Bosch spark plugs based on my own experience and proven specs.)

My Prius has had intermittent misfires for a long time (89,000 miles now). Maybe one of the original spark plugs died. After unscrewing more parts than I expected, I was able to replace the original 2006 plugs with these. Now it runs smooth as silk! My mileage has increased by at least 3mpg - from 42mpg to 45mpg. I have low profile tires and drive like a maniac so 45mpg is pretty good. I used a similar Platinum +4 in my 1995 Integra. It also ran smoother after that, but didn't get a lot of mpg.

I've been told that you should use a higher heat setting than they require. So I did. A 130,000 mile 94 Trooper will run like new with this connector and 8mm cables. It's hard to tell how much power has increased as I've put them to use, but it feels smoother at idle and acceleration is slightly better. There are some hills I have to climb to get the car's top speed to 62, but I can get 68 with these. So something better. First I switched the wires and they account for about half of the…

I replaced my iridium spark plugs on my 2008 Hyundai Santa Fe 2.7 V6 with these spark plugs. And wow. I noticed an immediate improvement in engine performance. It responds much better to acceleration and feels like new (at 100,000 miles). They were also easy to install. The only problem I had was that when I put them next to the OEM plugs that came with my car, they were shorter in the threaded area. After talking to a mechanic friend, he said that because of the 4 zones it doesn't have to be…

I love these spark plugs, have been using them since the product came out about 8 years ago (give or take). Bosch Platinum 4 spark plugs are gapless so you don't have to mess around with gaps. The four pins provide a spark every time (no misfires) and allow you to place the spark directly on the tip of the candle for better combustion, which also increases candle life with less carbon buildup. I've been using them for 6 years and have never had a misfire. In fact, the only reason I decided to…

So far so good. I installed these spark plugs in a 2006 Toyota Sequoia. Immediately after starting the engine after installing these spark plugs, there was a noticeable change in performance. At the time of this review, my car is running very well. I don't know if it worked better than after changing the spark plugs. This is the second time I have used these spark plugs, the first time was on a Dodge Intrepid which I owned for ten years prior to sale and I have never had to change spark plugs…

This is where I learned the hard way that just because Revain says "It will work for your car" doesn't mean it's recommended for your car. I bought this for my 01 Corolla because I have had good experiences with Bosch products and trust them as a manufacturer. These plugs are made from high quality components and they fit my Corolla, but it ran horribly and I lost a lot of g-force using these plugs. Then, after reading a few forums, I realized why the 4-pin design was NOT the benefit I thought…
