Owner reviews for spark plug

And timing belt, and spark plug change every 90 K miles or so.

I went with iridium's,and like the millage ,performance...

With the BKR5EKU plugs I got apx 27-29 mpg. All stock except for a neuspeed chip.

i use NGK G-power plugs in all my vehicles and they are the best ive found. they are about $2-3 tops and last forever, i have no complaints about the performance either.

I got on my last long trip 29-30 mpg doing 75-80 mph

I've been using Bosch FR8LDC in my car for years with good results.

Now running the Bosch +2 Platinums and my MPG jumped from about 21 to 25! A lot of others will tell you not to mess w/ the platinums but they are doing well for me.

Napa usualy is the only parts store around me that carries NGK in stock

I've had nothing but trouble with the Bosch plugs, from their cheap-o line to their IR Fusion line...

Don't go with Autolite XP iridium. I had on my Jetta and one of the tips basically melted after 25k. They suck.
