I just got my performance chip from Troyer the other day and it's awesome. I was reading through their manual and they recommend changing the upstream O2 sensors every 30k miles with Bosch. (I'm at 29k miles) I went to Kragen's and the OE Bosch brand costs $140. Is there anywhere online that has the OE (not universal) Bosch O2 sensor for cheaper?

On a separate note I'm planning to take out my spark plugs at 30k miles. Can I just take them out and clean them or should I replace them. If I clean them, what cleaner do you recommend? If I replace them, the only spark plugs I found available for my truck are the motorcraft ones. I have a 2005 5.4L FX4. Sorry if I suck at searching but I've searched a while and couldn't find congruent answers for these questions for 2004+ models.

Thanks,

Nick

 

My friend just got his Acura oxygen sensor... I don't know though if it was a OE Bosch O2 sensor and I forgot to ask him the price and the store where he bought it, I guess I have to ask him this weekend... Anyway you don't need to replace the spark plugs, you just need to clean it. However, it is good to remember that spark plugs are a wearable item, so it's important to make sure you check to see if it's worth cleaning before you go through the cleaning process.

In cleaning it and the firing end is wet, make sure you clean the spark plug with a quick drying cleaner. (Examples: contact cleaner or brake cleaner).Sand blast the spark plug using low air pressure and use a dry compound. Completely blow all the sand from the spark plug. Using a wire brush clean the threads and e-gap. I also want to warn you that insufficient cleaning of the spark plug may lead to spark plug failure in a very short period of time. Clean the spark plug thoroughly to avoid problems later. Remember, if a spark plug is fouling it's usually a result of engine side factors or incorrect heat range selection.

Good luck!!!!

 

NAPA had the Bosch O2 sensors for 98$ each last week.

 

Where is the oxygen sensor located and how to install them?
