if i put a sparkplug fouler on it will it make the car run different??? i've heard that the cel will confuse the ecu...i have a check engine light... and what size do i buy from the auto parts store??? is it a 3/16 or a 14mm????

 

If you don't have a test pipe don't do it. You will gain nothing!

 

You need an 18mm

You may even have to put two together. My '06 seems to a be a tad more sensitive than my '03 so I had to extend it out furthur. Even with that, it has sent a code twice over the past 18 months.

 

i do have a test pipe... today i tried with the 14mm but it was to small and short... 02 sensor came out too long... im guessing it is a 18mm...

 

What do you mean I am guessing its an 18mm? .... did you read what I wrote?? ...
