New 3rd Gen To Do List

[Justin727]

Du, for as many years as I've worked at a dealership and from my own personal experience I will never run bosch anything unless its a VW, audi, volve, etc.
I have seen an alarming # of people throwing bosch crap in their jap and domestics and had nothing but trouble. This comes from years at Toyota and Nissan. Toyota recomends Denso Nissan NGK (both are the same).

My personal experiencs years ago with Bosch Plats was in my Turbo Supra(stock). After my 3rd oil change I experienced a miss and detonation while in boost. I tried everything from changing coils to brands of gas both 93 octane and I still had the same problem.. I pulled the plugs and they looked burnt.. So I stupidly replaced them with more bosch and around 10k miles later same symptoms...

I then took them out and they looked more burnt then they did before. I then went and bought NGK plats and up till I built the motor 45k later never had the problem agian.

Researched and found I wasnt the only person on Supraforums.com to have the same problem with bosch.
Fast Forward to the present with the amount of boost I'm running I am using Autolite Coppers aka Motorcraft plug used for fords. I have to change them more frequently then plats but they burn hotter. So I'm not all OEM man lol.

Like I said you're probably 1 of the few that your vehicle may not be bothered by the bosch but I wouldn't.

But after my experiences and dealing with people over the last bunch of years bosch is simply a shot in the dark when putting them in anything else besides what they are actually meant for.

Du I'm not bashing ya brother but I wouldn't go around recomending bosch for any vehicle besides what I listed above.


BTW alot of the newer plats are recomended for change every 100k miles

FTW... dude, if your replacing NGK every 3 years thats early... I know LINY and TheRedMonster both got more out of their NGKs... You have a problem with something if you are burning thru any decent plugs that fast... I havent had a bad idle... like ever...

but to each his own I guess...

Let me rephrase that, I ran some NGKs for 3 years and they were still good when I replaced them. All 6 looked fine still, I just replaced them because the manual says inspect or replace every 2yrs/24K and I had new ones already waiting to go in and they were like $3/plug. From the looks of it, they would have probably lasted 100K though. When I bought the truck way back when it had original NGK/Densos in it w/ 90K miles on them and they still were useable.

I do not know why, but the rule of thumb is to use Japanese made plugs in a Japanese car and the European made Boschs in a European car.

Also, definitely do the Tundra upgrade if you need new rotors. My stockers are warped after about 20k miles according to my records. I also replaced my radiator with an aftermarket one due to the tranny cooler problem. Mine did not break, but I didn't want to take a chance. Check your rear heater lines also to make sure they aren't rusted.

Then you changed them @ the correct interval. @ $3 a plug you had coppers. Usually around 30k they need changing. :cheers:
