NEVER EVER install Bosch Platinums.I bought a set of Bosch Fusion Platinum plugs and installed them. Is anyone using them. What do you think of them?
06 Chrysler 300 Touring 3.5L
For one, I said the Bosch are inferior to the Platinums you have already installed in your car. Bosch platinums are the problems behind many engine misfire problems from several manufacturers. People think that just because they are Bosch, means they are a good plug when most people that know anything about spark plugs run away from them as fast as they can.I have 76000KM's now and dealership said I need to replace.
How are the OEM's inferior to Bosch Platinums?
You need to pay a little more attention.I might be a little confused or maybe the cars are different in Canada. I know my car came with Copper Plugs and my service manual states to change them out at 36k. I changed them out myself so I know they were copper. However, when I went to an auto parts store to get them, the rep questioned me about why I was changing them out so soon but I am 100% sure that's what the manual says. He then told me his computer showed that our cars come with platinums and tried to get me to buy some. Luckily, I had read up on this site before getting them and knew to only get coppers. There were a lot of posts from people stating to get copper and not platinums due to issues with plats.
SRT8's come with platinum plugs as well. The reason the 5.7 hemi doesn't is because of MDS I believe.You need to pay a little more attention.
He has a 3.5L which has a plug change interval of 160,000kms. You have a HEMI with copper plugs that have to be changed every 60,000kms like me.
The 3.5L and the 2.7L both came with platinum plugs.
My info was derived from the service manual from Chrysler headquarters which is what all honest dealers use and you just got suckered by a dishonest dealer. Plus now you are trying to convince yourself that you were not and foolishly argue on their behalf.Aparently it depends on how and where you drive the car. Also it depends what maintenance schedule you are going by. I put on 20K - 25K in 6mos. You are required to change out sooner than someone putting on maybe 15K - 20K a year and weather you drive a lot of short or all long distances. Guess that was what the dealer was considering.
I find the car runs pretty good so far. I will pull them soon to see if there is any black or white on the tips.
Because they thought you would have them swap them out there and not yourself.:twak: My origional post says "I bought a set of Bosch Fusion Platinum plugs and installed them." Dealer did not get a penny from me.
