Hi,

I put Bosch Platinum spark plugs in my car a few days ago and now there's a noticeable problem when I go to start the car. Should I just pull these out and replace them with NGKs? Could the plugs be causing the problem or is this just a bad coincidence?

Thanks,
Matt

 

i would pull them and replace them with ngk coppers or platniums. many 4th gens reported problems after using bosch plugs. they replaced them and the issues went away.

 

What type of problems are you having when you go to start your car? Any noise, hesitation to start, etc. I just put them in and I haven't noticed anything unusual?

 

I notice a hesitation. I've never had the hesitation that most 5th geners experience and now it takes an extra second or two for the car to catch.

 

Don't use Bosch plugs. Stick with NGK plats or coppers.

 

I put in NGKs and now the problem is gone. No hesitation at startup.
