Just trying to check with the community to see if there is a better set of spark plugs to purchase out there.

**Pulstar Iridium Pulse

*NGK Plugs

Denso Iridium

Denso Extra long life

AC Delco Professional Platinum



Does it really matter which ones? I have read conflicting things saying spark plugs are spark plugs when dealing with reputable names but themn I have read that Iridium is the way to go.....Any advice or knowledge?



Also I need to do some research but how difficult is it to change the spark plugs in the 2008 Tiburon GT Limited? Fairly easy for a novice?



Any and all advice/suggestions/help is ALWAYS much appreciated!

 

For the most part, spark plugs are spark plugs.

Rare metal plugs (iridium, platinum, etc) offer longer life than the plain ol' plugs, but they also cost a lot more.

You can replace $0.99 plugs every 5000-10,000 miles or replace $10-15 Irridum plugs every 100,000 miles. Cost is the same, performance would be the same.



Now, there are various spark plug designs out there. Splitfire, V-Groove, +4's etc..etc. That offer multiple ground electrodes. They claim more power and longer life. In a perfectly functioning ignition system, spark plugs won't gain you more than 1% @ best. @ worst they can actually hurt performance. Now if you have worn/fouled plugs, bad plug wires or weak coils, then an "improved" spark plug can improve the engine's performance, but it's not FIXING the problem (except in the case of worn/fouled plugs). They can also impair performance if you end up with "resistor" style plugs in an ignition system not designed for resistor plugs, or an improper gap, improper temp range, etc..etc..etc..



You can buy 99 cent plugs, just replace em when they get worn. You can buy $15 plugs and they will/should be worry free for the life of the car.

It's just a matter of what's important to you. Not replacing the plugs every 100K? or being frugal with your money and get 99 cent plugs, but free with your time, spark plug changes take time, and time ain't free!



Spark plug changes are a tad more complicated on the V6 compared to the I4, but they are easy enough for a novice to do. I always advise that you get a factory shop manual or at least a Haynes manual(shop manual preferred) before doing ANY maintenance on your car. Make sure you do it right, and using the proper torque values(always use a torque wrench on plugs!).

 

Random,

Thank you very much! I really do appreciate that clarification. I am very interested in doing the plugs myself so I will try to find a shop manual! Thanks again Random!

 

<-- too lazy to check . . .



Is it not listed on hyundaitechinfo?

 

WOW...Just went to the dealer with Some NGK Iridium IX's to have my plugs replaced. They came back and said it was going to be about 300 dollars to change my plugs. Said their manual says it should take the mechanics 3 hours to change the Spark Plugs.

Sounded like a rip off from what I have read on here.....What do you guys think?

Is changing the Spark plugs in the 2008 Tiburon V6 that hard?

 

I think you have to pull part of the intake manifold to get to the back 3. That may take a bit, 300 .. ouch.

 

A set of plugs for a transverse mounted V6 is WAY more involved than for an inline 4.
