What Spark Plugs are best?

CaliberMan71 · #1 05-28-2008, 05:06 PM

I am trying to find out what spark plugs will be the best for my 2.0L Caliber SXT CVT. I am looking to increase my mpg not so much power. If anyone has ideas, or can help please post, thanks.

This is a topic of some interest for me as well. Stock they came with the NGK's which I believe is good but with all these different plugs out there it'll be nice to know. For a good spark plug I would think that having better mpgs will mean better power in return, hopefully take less to make the car more responsive. Maybe soon someone will have a plug/coil pack setup. However must admit this car with the stock ignition idles very smooth, can't tell if the engines running at times.

I can always hear my engine running

. I had to replace the stockers at 50000km as the manual suggests, and I got an extra .5mpg out of it I think. Engine seemed more responsive overall, seemed to have more power and ran smoother. I used Bosch Platinum Plus plugs at about $16cnd for all 4.

I totally agree. One day I thought my engine wasn't even on. One time a friend was riding with me and thought it was a Hybrid because it was so quiet.

I've used a lot of different plugs in my car (before my Caliber) had people tell me that it makes a difference or that it doesn't...

From experience the bosch platinum (either the 2 or 4 but i would go with the 4) has given me the best performance over all. again this was on a Jeep grand cherokee, however when it's time to switch i will be putting in the bosch platinum 4's ymmv

youd do fine with the 2's honnestly. the 4's are just a marketing gimmick. electricity will take 1 path only (shortest) so it will not come out of 4 electrodes....physically impossible.

I just installed a set of NGK Iridium plugs. I noticed the idle is much smoother than the stock NGKs with 50K on them, and the pedal response is more noticeable. I haven't really put many K's on them yet, but I'm doing a trip to Ottawa this weekend, so I'll report back on the MPGs.

Well, the news is good so far. Before I installed the NGK Iridiums, I was getting about 26-29 MPG mixed driving, after the two fill ups between Oshawa and Ottawa, I got around 32-33 MPG. This was a lot of highway, but also a good amount of local driving around Ottawa. If you have the extra cash burning a hole in your pocket, I would give the NGK Iridiums a try.

I did my 30k tune up and put in a new filter and some Bosch Platinums and ended up with 33 MPG as my average for a while. However, it has now fallen back off to normal at 44k...
