its almost time for me to change my spark plugs and i was wondering where everyone is buying their replacement spark plugs. i know our stock ngk iridium spark plugs are basically the best you can get, and i want to stick with the stock ones.

on sewell its 13.98 and 12.44 with our "clublexus" discount. is there any other site that offers the same spark plugs for cheaper?

 

I read in one of the other threads Pulstar plugs had gains. Has anyone tried them yet?

 

i read about that too when i did a search. however im not totally convinced about the gains, i find it very hard to believe spark plugs would ever be able to net you any hp.

 

is there a DIY for this? you can try pm'ing kerry at lexus of westminster

 

e3 plugs I think they are called... like +8hp proven on an engine dyno... seen it on horsepower long time ago... when I change my plugs I'm gettin these

 

so no one has any ideas where to get the stock spark plugs for cheap other than sewell?

 

its 12.44 already how cheap do u want it... thats like going to buy fast food man who cares if u can get it for 1 or 2 $ cheaper lol.....

wat a funny thread

 

any recommendations on who i can get to install my spark plugs? i dont want to DIY and im assuming the dealer will only install theirs. btw im in houston.

 

stupid question, but the is it $12.44/plug or for all 6.

 

here the gain on Pulstar plugs

Nice gain, I wonder how accurate their dyno's are info is.

 

that price I believe is for one.

 

I've never done it on an IS but its probably just like any other car.

1. Take of engine cover.

2. Disconect the coil to the specific cylinder you are working on (do one at a time).

3. Remove what ever holds the coil down to the valve cover.

4. Remove and install new spark plug.

There's you DYI.

 

sometimes its not as simple.. like for my 2GS i had to remove a million things before i got to the coils

 

your right dont forget to remove intake or easier access i put a set of pulstars on a integra daily driver i have and threw a check engine code. lol Pulstars FTL!
