Boxster 2005 spark Plugs

Recommended Posts

If there are any experts in here, can I know after how long should we consider changing the spark plugs ? and by not changing the spark plugs how does it impact the cars performance/engine ?

I have a Boxster S 2005, 100.000 kms done.

Best regards,

I am actually no expert on Porsche but can help you understand the spark plug theory, as it is used only to create a spark inside the combustion chamber. Every spark plug is timed based on the kms associated like normal NGK and Bosch lasts for 10k-20k kms and advisable to change in every alternate service (In Japanese, as I have Lexus). Sport performing plugs like Platinum have double the life of 40k kms and Iridium one (most expensive) have 80k kms life.

For cars that is difficult to change plugs like removing the manifold and all top parts removal is must then its better to choose long life plugs. Also long life plugs give better performance by giving good quality spark, if they are installed with good HT leads (plug wires).

For your Porsche you need to check which plug is recommended and which one you got in last service as to decide what next. If none of the info is handy, go old school and get it open and checked by good mechanic who can advise the condition of spark plugs and recommend to change or not.

For change frequency elvis is quiet right in above explanation.

By not changing spark plug in time, you will start missing the engine performance especially on low revs initially and then across the full power band. You will feel rough idling and sluggish response if plugs are not change in time.

Better go here and see what you have: http://www.ngksparkplugs.com/part_finder/car_truck_suv/default.asp?mode=nml

Changing plug in any Porsche is not too difficult and it's not too easy, it's a reasonably moderate job and experience mechanic can change all plugs in less than an hour max.

Which boxster you got: 2.7 or 3.2...? and how come 2005 model hitting 100k now, rarely driven or you just bought it now?

I agree with milane on response will be bad, but my advise is to opt for iridium long life option than other standard OEM is only for increasing the schedule interval and saving time. Csot diffarnce is not very high 15-20 dhs vs 35-40 dhs.

Thanks guys for you responses.

I am getting genuine Porsche spark plug for AED 90 I have not purchased it yet. I am checking with other suppliers as well.

@ Milane -  I have 3.2. I bought it October last year and this is my weekend car and rarely used.

You can get NGK from any sport or performance garage here in Dubai, call few good ones max garage, robbies, Icon auto, ramy trading etc. Just make sure that you select the right one as per NGK product manual.

Boxster2005, call that faour guy and visit them as they have very good solution for Porsche as that guy (Abu hassan) himself is a porsche enthusiasts, and only deals with Porsche servicing. Make sure you call and discuss spark plug change prior to appoitment so that he can arrange plugs if he don't have same for your car. Pretty knowledgeable, humble and genuine (honest) guy.
