This has been a very much under reported subject but it seems replacing the 996 TT ignition coils every 3 years or so is far more important than replacing the spark plugs. The guy who bought mine did this and he says it now goes like a rocket, they are cheap too

a good point, but would suggest that changing spark plugs is equally important as changing coils if not more so. in fact, most will probably find that changing coils to plugs at a 2x to 1 ratio will better serve them. especially on a "tuned" car. however, anytime you change plugs? the coils must be inspected for barely visible hairline "cracks". cracked coils will exhibit misfires and breakups in more dramatic ways that simply "burnt" plugs can or will. in my experience.

so yeah, coils crack and plugs get fried. in 3 years i would change my coils maybe 2 times to plugs 2-3 X. works for me. but they ARE cheap preventive mainetance, so.. good advice!

I don't know that it's "under reported".... Pretty common knowledge that our coils don't hold up very well, particularly in tuned cars. Also, not 'more important' than spark plugs, as 996 Turbo's, especially tuned ones, go through plugs pretty quickly as well.

Change the plugs AND coils much more frequently than the factory suggested interval for best results. 997 style 'long bolt' coils also seem to be less prone to the cracking than the original 996 'short bolt' ones.

the original 996 coils are not made any more. we've been using the 997 coils for years now, and they *usually* come with the ( 2? ) necessary longer bolts supplied. when you order them, just make sure the bolts come with. some sets do, some do not.

you'll also have to slightly manipulate the heat shield to make them fit. i think pwdrhound (?) has a "how to". might want to PM him and ask. there are also threads re coil replacement that would include this info.

I changed my plugs and coils out last month, used

Depends upon the mileage covered and as others have noted whether the car is stock or fitted with a "tune".

I have had the plugs changed a number of times in my 2003 Turbo (currently with 160.3K miles). Never made a difference. At around 140K miles I had both plugs and coils changed. Made a difference.The engine ran better. The original coils didn't look bad -- California car so no snow/ice/salt -- and there were no signs the coils were bad. But the engine ran better afterwards. The coils were the difference.

But the engine also ran better after I had the O2 sensors replaced at 132K miles. In this case on sensor was tripping an error code and I had all 4 orignal ones replaced.

Anyone changed a set of okada / ip coil?

Richard.

the guy also put GT2 spark plugs in mine, is there any difference to 996 TT spark plugs ??

Since Porsche has substituted the old 996 coil packs to the 997 packs, the packs hold up a lot better. The newer coils use a better composite material to ward off the deterioration! The 997 coils dont crack as much, my opinion, last a lot longer than 3 years!

change the plugs regularly and the coils last a lot longer....

Yep this is one of my #1 selling items for the 996tt.

Jason,

I know you just did lots of work updating your web store, but I still have nothing but aggravation using it... LOTS of clicks to get to any actual parts, very slow with frequent and long "Pease wait while we ready the page for your lookup" messages, and a zillion sub-categories, then sub-sub-categories, and then often sub-sub-sub-categories that you have to select to through (and wait for the slow page load) before you can actually see what you do sell for a 996 turbo. Many of those categories are empty or have a single item once you do finally get to the end of the chain!

I know your prices are good and you are a Rennlist vendor, would love to do business with you guys, but boy it would be great if I could load a single page that showed me all the OE, OEM parts that you carried in one or two places!

For example, I recently needed a Turbo check valve. On your site, searching for the part number 996.110.135.70 (after a ten second delay) gives tons of results from o-rings to brake pads. Perhaps everything with a 996 in the part number? Useless.

Searching for 99611013570 without the dots gives no results. OK, lets try a manual search...

*select Porsche (delay)
*select 2001 (delay)
*select Turbo (delay)
25 categories given... Would it be under 'emission controls'? 'air and fuel delivery'? 'Engine'? Let's try emission control..
*select Emission controls, hit search (long delay)
25 more sub categories given! Would it be under 'Vapor canister'? One of the four additional 'Vacuum something' sub categories? Something else? Let's try Vapor canistor as the check valve is really used to purge the vapor canister.
*select Vapor Canister, (long delay, 'loading results')
One item given, not what i'm looking for... Try another sub-category
*select Vacuum connector, (long delay, 'loading results')
Again, a single item given. not what i'm looking for. Lets try another
*select Vacuum line, (long delay, 'loading results')
Nope. About ready to give up... lets try under engine two categories up.
*select Engine, (long delay, 'loading results')
54 sub-categories given! Let's read them all and try 'fuel tank breather valve'
*select fuel tank breather valve, (long delay, 'loading results')
Nope, One item given. Not what I'm looking for....
Now I do give up.

This is basically my experience every time I try and find a part on your site, 15-20 minutes of searching, giving up and still having no idea whether you actually don't have the part or I just couldn't guess the right category, sub-category, sub-sub category you had the single part listed under...

I've probably purchased $5K worth of Porsche OE or OEM parts in the past year or two from local dealers, local auto parts stores, Suncoast, Sunset, Sonnen, Pelican, and RMEuropean and others, but nothing yet from you guys though I've tried several times... I'd love to use you guys in the future, but there has to be a better way to find out what OEM parts you do and don't stock for a particular vehicle!
