Question re: K&N Air Filter installation
I plan on replacing the stock air filter on my XK8 with a drop-in K&N Panel Air Filter and was wondering if anyone had to remove the air box to do it. I'm thinking the K&N installation is just that. A simple swap out but the K&N instructions say otherwise. The instructions show an additional rubber seal which needs to be adhered to the air box lid and to do that the box needs to be removed. Is that necessary? Could someone that has done this before chime in and let me know before I start wrenching away? Thanks in advance and sorry if this sounds like a lame question and I hope I don't start a discussion on K&N air filters.

the filter frame might be thinner and requires a spacer gasket to make a good seal. you do not have to remove the air-box to do this. simply remove the cover by separating it from the intake runner; there is a clamp. i find it easier to remove the two bolts attaching to the throttle body, the full load breather and the MAF plug, off with the whole assembly, a minute to do. don't lose to seal at the throttle body. the box sealing clip under the intake runner is a pain, made a tool out of a paint stick.

It's my understanding the XK8 and XKR already has a stock cold air intake set up. The cone style intakes I see in some of these cars sit in the engine bay so I would think all they do is suck in hot air which can degrade engine performance. I could be wrong but then again........
In this case you're right. The cold air intake function has been lost.

All I can say is that I have driven the car with this and the stock filter on and both feel just the same to me so i can't really say there is a downside ,you do get a lovely rasping sound on acceleration though,wouldn't advise anyone to buy one for the difference it makes unless it's a bargain buy as this was

If you received the right filter for your car it should not require an additional seal however, things have a tendency to change with time. You should be able to identify if an additional seal is requires simply by looking at the old and new filters together. FYI I prefer the cold intake!
