BOSCH IRIDIUM FUSION SPARK PLUGS
so i bought my box in mid march in 05 with 1 mile - now 2 years later and 28,000 miles later - i noticed that the mpg's and the performance wasnt what it use to be - so i figured time for some new plugs oh and air filter - so i went with the BOSCH IRIDIUM FUSION spark plugs (part # 4501) they were $9.99 each (pep boys) - when i removed the old plugs they were pretty bad so im hopeing i see a difference
well heres my plan i was rideing on E so i went to fill that tank - now im gona ride out the tank and check if i notice a difference in my mpg's - i can honestly say that at idle it seemed alot smoother and acceleration was a little crispier - before the fill up i did the math on my last tank it was 25.8 mpg my last fill up was the same thing - so like i said in about 5 days il see what this tank gets and see if there a big improvment

your not gonna see much difference from plugs.
plugs are recommended to be changed every 30K anyway so your just about on time. don't believe a plug is "pre-gaped" its a bunch of bull.
i got my 4 toyota plugs for less then ten bucks and gaped them and car runs better then it did before with the BS plugs i put in it. i don't remember the brand off hand.

recomended i thought it was 30,000 and no sparkplug last forever i do know that most toyotas have 100,000 mile plugs - i would never leave plugs in my car that long but thats just me

alright im at half a tank right now and i have 167 miles - i havent seen that kind of mpg since i purchased my car - i also noticed that the low end torque seems a little healthier

dam your at 167 at half tank, i could never get that mileage... Heavy foot?? MOST LIKELY!! I gotta stop beating on my xA... I go through a tank of gas about every 5-7 days depending on how busy my life is at the time. Sometimes i can go 2 or 3 weeks without filling it up again.
At half tank on average i'm at 110-130, and 140 on a good day.

you guys failed to see the point of this thread - i was never expecting to see a hp increase i was hopeing to freshin up the hp the motor already has and yes the plugs did make a difference im getting 27-28mpg's which is better than the 25-26mpgs i was getting the idle was a little smoother and the low end torque felt a little healthier 2-now keep in mind that my car already needed new plugs so im not claiming that the bosh plugs are better than others
like i said before your not gona get any real power with out major mods i would never bother spending money on a intake,header,and exhaust theres no real gain there - kiddies save your cash and get NOS

Like I said....don't waste your money. I am getting less miles per gallon than I did with the old plugs. I am going with the guy that says save your money and buy normal copper plugs. I never did this for HP either. If I wanted to gain HP.... I'd go buy a Vette.
