spark plugs

hi, I am going to do the spark plugs on my 05 with the water pimp,etc very shortly



I was wondering, what plugs should I use? stock or? seems that the bosh ones are causing problems. Suggestions?

i was thinking the Bosch (4501) FGR8DQI Platinum IR Fusion Spark Plug, but people seem to be having problems with them in asian cars. Seems like denso or ngk might be the ones to get. suggestions?

I would strongly advise against using Bosch plugs on anything with an internal combustion engine. Use some Denso plugs or NGK. As far as the water pump goes... The newer generation Avalons water pumps are very good quality and very seldomn have to be changed. If you still find you desire to change it, do yourself a favor and get a Toyota pump.

All new Avalon's come with NGK Iridium spark plugs. These are the highest quality you can get. I have run them 100K on other vehicles. Your owners manual will show replacement plug part numbers and my 2008 shows them to be the Iridium plugs.
